They still have too many ppl for single game that is developed at current speed - that is the fact.
They have made this game failing all by themselves.
First of all you can not have a game without casual content. Currently only thing worth doing are raids. Over drops 3-5 they were slowly introducing content less raid oriented, that was actually worth participating and they have simply destroyed most of that work with D6. And even hardcore players spend different amount of time in game and sometimes they do want just chill, doing stuff out of raid, as long as it have any sense. Currently 80% of players logs-in 15min before raid and logs out 15min after raid, most of the rest do PvP.
Another issue is how long it takes for new player to actually start playing the game.
LvLing takes still too long. If you know where exactly to go, know the game enough to kill things efficiently, there is ExP event and you will use boosts from cash shop, lvling will take you anywhere between 5-8h, but a lot of that time you will spend in 5-20/25 area, it gives wrong impression how long lvling will take and without all of above it will take ~40-50h (~25h if you are more hardcore player), for most ppl it will take whole month to reach lvl 50, especially that lvling in WS is not engaging at all especially after lowering difficulty lvl.
After you reach lvl 50, you are useless. Unlocking character was good only when all started the exact same time and when only way to unlock it was by using EGs (so before original release). Currently it takes additional 40-50h of gameplay to fully unlock your char and that ONLY if you will go PvP and ONLY if you know what to do.
Gearing up new character is terrible you need over 90k prestige to buy full PvP gear and that is after you unlock your character first (well you should buy gear without imbuements first). So for average player it will take 2.5-3m to have lvl50 fully unlocked and geared PvP character. It is a bit easier in PvE, but there you need super expensive runes, as an old player I haven't ever realised how annoying it might be. On top of that in PvE there is major gear gap, you start with blue ilvl65 PvP gear (well if you know game white i50 items are enough for gold dungs), after that you need premade i65 group to learn anything on dungs and to get i80 items - that will not happen in 1.5y old game, so you can farm WBs, where droprate for items is just too low or.... Either be pushed once in GA or every day in dungs, alternatively farm gold in PvP for crafted gear - neither of that will help you learning game.
To start playing WS as normal player, that can spend few in-game hours few days a week you need at least 1.5m, most case scenario it will take ~3m. After that you need at least 2d/week that you can play for 3-3.5h straight and another 4-6h to farm gold for runes for your gear (can be even in 20-30 min sessions), this is fine, but close to nobody will invest 1.5 month to even start playing.
Another Carbine sin is release, actually both of them. They have lost a lot of players on original release, because of queues that led to making tons of servers, that were empty after short period of time. That I somehow can understand, but on what happened with F2P lunch there is no excuse. You know (or should know) what will happen with influx of players (there were data from original release) and you should prepare for that, even if you have failed - 2-3 weeks to fix problem??? This failure was responsible alone of loosing at least 90% of new F2P users, over 90% of come backs and even some players that against all odds were playing this game all the time since original release.
On top of that "Carbine knows better". Carbine fails to acknowledge and fix problems, that their community presents to them. Good example are arenas and PvP in general. Initial arena problem was balance, mostly because of gear gap, broken class combos and broken items with OP specials. What Carbine did was fixing issue for over half year, meanwhile most ppl that were playing only BGs stopped playing, because you couldn't compete in 1.5k BG gear with 1.8k arena gear, arenas queues became so deserted that nobody wanted to play them any more (it can not be funny playing same team every day for Xh, for few weeks). So obviously after they fixed gear, they have great idea to make 3v3 rated only way to play PvP - that would be fine, but ppl were mostly queuing solo for 2v2 before and it is always easier to find 4 players, than 6. That wasn't even that bad, the problem is Carbine was and is trying so much to make arenas more populated, that it ends with ppl not queuing BGs. Obviously a huge problem with BGs were bots, it took "only" 2m to get rid of them (I am surprised any1 was queuing BGs at that point), but currently to complete weekly quest for costume token (only reason to even play BGs - contract rewards are not attractive, prestige is useless, gold is useless, there are no player ranking, nor rewards on the end of season) you need 40 wins, so in theory 80 games, so at least 800mins/week, nobody will invest that time, if same you can have win trading arenas for 2-3h. Ths is only example, but it works exactly that in many arenas of the game.
Finally the whole F2P transition.
You CAN NOT have F2P game without cash shop....
Even now half year later there is nothing decent to buy there. This game have so much potential with CS and literally nothing have been done.
There were single claim mounts at price of account wide unlock in most of other games and most of them are just reskin of same model.... Now we finally have account wide months, but they are extremely overpriced.
Costumes.... if I could mix up pieces from different costumes I will maybe create 3 decent ones and one of the would be differently coloured medic costume from GA. I recently logged in to see GW2, I would buy ~80% of costumes there, in WS my count is 0.
Housing - probably biggest failure. Remodels on ground and sky are fine, but there should be 10x more of them. Not to mention we don't have any music remodel, we don't have house skins etc. But decors are disaster. Nobody will buy single decor for 1 euro, if sometimes you need dozens of them to create one object on housing plot. How it should look like? Currently most (if not all) decors for house plot are object you can find in your journey across nexus, if you will start looking soon you will realise many of them are just not available (as dominion I can easily find 5+ standing by the contracts board). Fist of all every single object in game should be in CS as decor. Second most decors should be sell as account bound housing plot vendor unlocks in themes of 50 decors in each theme for 800-1600 NCoins. In each of those should be 1-3 expensive (3-5plat) decors to boos carbine profits from CREDDs. Every single theme should have at least 2 equivalents with different decors (ex. Dominion1 Decor Pact, Dominion2 Decor Pact, Dominion3 Decor Pact), there should be theme for every major fraction/race in-game + some general (electronics, trees/plants etc.).
Knowing how many players are into housing in WS, how many of them are spending a lot of time there, how many of them are creating thematic houseplots and replacing all decors from time to time, housing could alone create enough cash flow to make WS one of the most profitable MMOs out there. And let's face it, all decors are already there, so saying it would be cheap and rather easy to implement is a fair statement. Instead we had F2P transition without CS. I have no idea how carbine wanted to make $ out of the game, same as I have no idea how they have make more after F2P, than in last quarter of P2P.
