Launcher is bugged. When your game can't even launch properly don't expect newcomers to stick too long.
Party quests haven't reduced their party size requirement or increased their rewards. They are useless at this point and its not a hard thing to fix. Make their rewards heavy stat boosters for a limited time like the Mu Lung dojo or something.
Post 200 is still a huge grind with very little flavor. For the most important part of the game it goes at a snail pace.
Bots everywhere, tens of thousands accounts banned for hacking and yet they refuse to deal with their decade old code and find what vulnerabilities they are using. You got programmers right?
Useful Items is butchered, why?
No compensations for their major screw ups, just a "Thanks for your patience".
Older areas haven't got any clean up or incentives to play at, party questing would do wonders here if they made the rewards useful.
Non-KMS content is getting removed, not getting fixed, and quickly getting outdated.
Shameless updates to Cash shop while the rest of the game is on fire. You won't get money from virtual cosmetics if you have no game to stand on.
Quietly add cooldowns to crafting and auction house that weren't on the patch notes. What else have they changed that we haven't been told about?
Heavy lack of communication. I doubt GMs have such busy lives given the state of the game to at least make a memo once a week.
When was the last time a major update didn't get extended?
Jett, broken since birth.
Removing old areas for no good reason like Tera Forest, Florina Beach and Chryse.
We never got Hekaton making Tyrant Gloves impossible to get (and since I know someone will pick on this, 400 days of invasions is impossible for normal people)
Making bosses daily once instead of twice is stupid, making all difficulties share the same entry is just as bad.
No pottable badges, not even the Black Mage's one.
Singapore being axed.
Dimensional Mirror not having NLC or Momijigaoka despite how annoying it is to get to those areas. We had it good before they decided to change it for no reason.
Team copy pastes KMS updates which leads to issues. Change whoever tests your game because its not showing. GMS is not KMS and will never be, do your work.

I have stuff to do so I'll stop here.
