I had just finished a quest, and was on my way out of the area when I found a rather amusing cosmetic bug. I know things like this are going to pop up every now and then with it being so soon after the release, but I thought I'd mention it anyway.
I am not spending a single penny on the game until changes are made to the game that I want to see.
1) Remove having to be in a guild to sell items to other players at a kiosk.
2) Cosmetic modding for armor and clothing.
3) Difficulty slider.
4) Fully customizable player housing that isn't tied to anything in the game other than having the correct resources and enough gold to build. Don't tie it to PvP, guild membership, or anything at all. Oh, make it instanced so as not to take up world map space, too.Zeni screwed this one up already.
Any /one/ of these things implemented would get me spending again, maybe even subbing.
