I'd like to see setting-appropriate skills for the core professions, not just renames of old skills, except, maybe, for a few, to demonstrate carried-over knowledge. Unless, of course, the story has characters starting fresh off the boat in Elona.
I'd also like to see more incentive to actually roleplay, or at least get involved in the story. Actually, I'd like to see a good, deep, immersive story. Outcast god come to wreak havoc and vengeance on an unsuspecting continent? It's got potential, but I'm not holding my breath.
And while this isn't something the developers can really do, I'd love it if people in Nightfall (and Prophecies) would bring one self-preservation skill and use it. Maybe then there'd be no groups shouting "5/6 LF Healer!" for an hour.
