The reason everyone is getting upset (point form i don't want to type an essay):
-Promises made that after a nerf, things will get looked at (please look at healer weapons and bane damage just to be recent)
-Things don't change, and the game remains the same and people are expected to just "deal with it"
-High end progression is halted, because just as you gain something, its ripped away. (see 4.3 weapons and the above two in first bullet, again to be recent)
-Progress again in current state of the game, repeat cycle
I have played this game almost 5 years, and this cycle is vicious and never ending. I think the vast majority of the older server population is not just lashing out at this change, it's just frosting on top of the icing on the cake.
Personally every time these nerfs happen, it makes me want to log in less and less, because I know it will just remain broken, you will get tossed a small bone and expect to keep trudging forward on to content that doesn't change, and was beaten "on tier" before all of the nerfs. Saying that you will balance the content later to make it in line with the changes is just to long a process, when you go 1 step forwards and 2 steps backwards every 3 months, it's really frustrating and makes you question why you even play.
Their is a lot of jargon in a lot of posts above, likely it will never be read again in 2 weeks.

R - Don't nerf things until you have the balancing factor ready as well.
example: Don't nerf riposte procs, until you are ready to patch and increase all other procs. Doing the first, without the follow up is really just.... Well you know...
