I am convinced that Anet devs cannot name a single piece of GW2 content where Elementalist is currently the best at doing anything.
Literally the only niche where it was "the best" at doing a small tiny thing in the game was in WvW by using Fire Staff 5 to do ranged damage to an enemy zerg. And Anet just nerfed the hell out of it.
It seems that Anet is determined to make Elementalist players give up on their class and play something else. I've been playing Ele since launch and it really does feel like choosing Ele is just playing GW2 on hard mode for no benefit. When I switch to my other classes I can play my rotations with half the speed and usually live longer while doing it.
