Lets not over react. They are fairly minor changes (which is good), and they target only some of the trouble fights in both 10 and 25 man. (seigecrafter for 10 man and klaxxi for 25 man are the major walls IMO). It's also been quite a while since SoO launched and eventually nerfs happen, this should be expected. Killing bosses after nerfs shouldn't diminish your enjoyment of the game or the kill itself. The idea is you did what you could with what you had and no one can take that away from you.
