Two suggestions: (maybe you've already thought about them)
1. Give everyone VIP access for 1 day. This will give us an idea of how good the VIP is. Like you mentioned in a previous post, once you get auto loot, it's freakin hard to loot lol. This will be annoying in parties too since I imagine the proc is based on last hit? So if a VIP autolooter gets last hit, the loot gets picked up and if not someone has to pick up?
2. Consider 3rd class change donation. I really don't think this has an effect on end game, but the damn class changes are the worst. I don't mind noblesse but 3rd class change quests can bite me. I'm sure others agree. It's hard enough when you have full buffs, but certain classes suck at farming and this makes the quest a pain in the butt, thus putting another gap between DD's and support. I guess there are some good things like pvp @ varka/700 but I still hate them lol.
