I don’t really know what you mean by more PvE going on.
Not really sure what you mean by good group content, but HoT has raids now, if that’s what you mean.
Condition builds work for everything now, due to a revamp of how conditions work.
The only place the game really has a trinity set up is raids, That said, If you think this game has ever been about every man for himself, you really don’t understand the combat in the game.
For example, in dungeons a lot of warriors take banners which help everyone. Guardians share their boons. Thieves can (and often do) stealth everyone. Rangers have spotter, a trait which buffs everyone in the party.
So I’m not really sure what you’re talking about about every man for himself. Admittedly there are selfish players in pretty much every game, but the game is designed so everyone can support each other.
It helps if you play with a regular group instead of pugging, but even in pugs, people tend to build to support their parties.
