Aside from the perma fall damage; they aren't really nerfing anything. They are trying to make the telegraphs for mechanics pretty much the same across the game. World of Darkness with the hydra dragon has the best example. A purple marker means to stack, but its a unique telegraph that no one understands and was never used in the latter expacs. Even people who finished the game don't really get it. So why not adjust to to a regular orange pointing in stack marker? Then new players can learn what that is and well.. yes they will most likely run away from the group; but people in the alliance raid will be telling them that is a STACK marker. Thus teaching the adorable sprouts how to play the game. I think that is wonderful, and they should adjust that with older content.

Dungeons such a Toto-Rak will be getting a graphic update. There might be a few others that will get it too. Who knows. However, I don't see it as a nerf; I see it as a upgrade. People start in ARR and ARR is difficult as it is with its older designs. They need to make this part of the game be the best it can be.
