As far as really specific suggestions about game-play go:

I'd like to see enmity changed to depend less on raw damage dealt and more on spells and abilities that deal directly with enmity. That's what the abilities are meant to do, yeah?

I would like this adjustment to merit caps to be reconsidered.

This isn't a suggestion, but I absolutely love the conglomeration of warps that can be obtained through Voidwatch and other means as of late. It just feels so good after years and years of watching my little onion-bro run around for relatively long periods of time.
