I think its fine, just the reduce the potencies.

I constantly see the argument that "There will be a disparraging difference between DPS's!". Main Scenario and Alliance Roulette fresh 50's already do considerably less than someone with max stats and they don't get kicked or recieve any grief. I don't see how this is any different.

Moving onto their third expansion with a level cap of 80, its inevitable that they make the original dungeons faster and less painful to sync through.
