People used to say the same about other skills. I mentioned on another thread how the nerfs on Crippling Strikes, Big Brawlin, morale pump tactics and other things affected Destro severely when facing a highly mobile Order group. And before someone says "but but ORDAH", i am pretty sure some nerfs there like Skirm SW, Dirty Tricks, Flashfire, WoH, etc. have surely affected some setups and their overall performance against specific Destro groups.
Stop with the unnecessary nerfs. Revert the previous changes made by one guy who had no clue. Then, when you can easily perma snare the Slayer and reduce his damage by 25% you will see that Rampage is not OP. Not one bit.
(I am 99% sure those changes won't be reverted, which is pretty sad... my intent with these posts is simply to stop FUTURE unnecessary nerfs).
