Changes to dragoon make no sense. They are trying to make a brainless class easier to play.
Lack of monk changes, despite thread after thread after thread FOR 2 YEARS shows they either aren't reading the forums (which would mean they are blatantly lying to us) or don't give a fuck what we think.
Lack of useful summoner changes show they are more prone to knee-jerk reactions than actual thoughtful adjustments. They nerf Ruin 3 damage and make a spell consolidation that NOBODY asked for, ignoring the many fundamental problems with 4.X summoner that EVERYONE has been repeating (attunement/aetherflow consolidation problem, heavy death punishment, flawed Bahamut AI, etc)
Warrior Shake It Off change shows the are willing and able to make complete and total reworks for abilities, EVEN ONES THEY'VE JUST RELEASED, so there's nothing preventing them from fixing monk and summoner.

They spend more time working on the trials and raids, which would be fine.

How is one expected to enjoy a good movie if their seat is made out of thorns?
How is one expected to enjoy these trials and raids if the class they want to play is poorly designed and not enjoyable to play?

The Devs don't care about the players anymore. They only care about their internal ideals about the game. This is how a multiplayer game kills itself.
