Can't say I feel that way OP, if anything I like the oversimplified threat "management" now because I can finally not have to worry about losing aggro when I get a low level dungeon in leveling roulette because the tank stance isn't unlocked yet.

For bosses, aggro wasn't really an issue even before outside of very specific mechanics (Neo Exdeath) so I don't really feel a difference either. I'm glad as a paladin I can actually pull and not have to do rage of halone which delays my entire rotation, instead of hoping my cotank is a WAR so that they can do that sick tomahawk > equilibrium pull.

I'm also glad all the tanks have a proper aoe rotations now, it actually gives me something to do in dungeons and keeping up my dps while mitigating properly, positioning mobs properly and avoiding aoes makes it more exciting and interesting. I'm happy I don't have to do Flash then bang my head on the Total Eclipse button anymore.
