I meant in relation with what I assume is Blizzard's attempts at challenging content. Like I said originally, I am pretty sure they put the power auras in and changed other things within the game in an attempt to let you watch the action, not your buffs. This would be against that idea.
Perhaps I just don't have the right addons, but I find the concept of watching buffs annoying. The way this change sounds though means it wont be a big deal. I guess I'll just have to see how it works. Really, because it will be a constant thing to watch for it wont be so bad anyway compared to, say a trinket that you use for a while and get used to only to switch it out.
