See, there's one of those areas where the Law of Unintended Consequences is going to bite them in the ass. There are a bunch of people that run old dungeons for twink alts or just for nostalgia or just to go blow things up that aren't the same old 5-man heroics they've been doing for the last 6 months. If they nerf things so badly that 85/90s won't be able to solo/3/5man old raids or roflstomp older instances the way you can today, they'll be disenfranchising a lot of people.
We'll see whether they consider that, or if they decide that Kung Fu Panda will draw in enough new people so it won't matter.
