Would anyone like to see the return of mana aget, amp/damp, or any other classic spells?
Depends.
Mana gems would need to make mana meaningful but it can’t be done in a vacuum. They would have to changes lot of other specs and not just casters. So in of itself, no. I would need to see the other changes. Right now mana for fire and frost is just a limiter on spell steal.
I wouldn’t mind seeing amp magic or damp magic return along with fire shields and frost shields etc. but right now mages are way to tanky so again I would need to see all the other changes would be introduced with it.
I kind of miss the different armor buffs between retail and classic. Even if it’s really just swapping between Ice/Mage Armor whether out farming in the world or in dungeon/raid content, I like the playstyle of choosing a buff depending on the situation at hand, almost like hunter aspects (I also love hunter aspects, so there you go.) They certainly wouldn’t play the same and would need to be revamped a bit for retail, but all the same I’d like to have personal buffs I need to maintain that aren’t solely DPS-burst-window buffs and aren’t only for a few seconds.
