With Ion going on about how they want to “save the beating heart of RPG in the game” I’d be nice to see class quests make a return, among other things.
I’m not sure that the playerbase would necessarily go for bringing back spells from it, but it would be nice to see some low level quests to give us a cool trinket, weapon, armour, or cosmetic for a class.
If they were a bit faster on making the sets, I’d say it’d be cool to do a sort of “heritage armor” for classes that required a challenging quest line. At the rate they do the races though, it’d take us several expansions to get it.
