I would assume its being setup for those with and without the expansion and at all levels. In reality people will only run them if the incentives are right. Incentives for running lower levels probably won't be desired as much. Placing them in the right place in itemization with the unreleased gear will be troublesome also. Its good that they are trying to include everyone and set it so in the future there shouldn't have to be a tweak every expac but with all the new inc stats/caps I hope they can get something solid that will last. My real big question is going to be about acension levels. Will there be some kind of control factor with those as well? I can see the manaburn having to be nerfed all over again with the 50% max damage and some issues with a couple other ones.
