What do you think was the worst thing this game experienced from 2.0 until now?

This works both ways though... what if there comes a point in the game that you dislike - which is very likely for all of us given how divisive things have been lately.

There's a handful of things about the game that I dislike. I offer constructive feedback where appropriate and if the game ever reaches a point where it lacks many redeeming qualities for me then I will take my leave. Far too many people fool themselves into thinking that they have an obligation to stick around due to the time/money investment that comes with MMO's. I saw it frequently back in WoW. I still have friends who play it four years after I turned my back on it. They have nothing but complaints about the game yet refuse to move on. When WoW stopped appealing to me, meanwhile, I simply took my leave. There's so many other things people could be doing with their lives instead of clinging to something that they no longer enjoy but feel a misguided obligation to commit to.

I think that's a very good and pragmatic way to approach things - and I do agree.
But I think that what is lost in translation over the forums sometimes is a genuine passion for something people enjoy, but can't quite articulate.
Feedback should be encouraged, even if it sometimes gets lost in a few badly written forum rants.
