Fairly early for this, but... Do you think APIs and Mods will be allowed in this game (ie: non-game breaking and nonbotting mechanics consistent with the EULA)? I am guessing no, some of the best development and toolsets comes from the user community, but are banned for various reasons. Also, the ability to change up your UI would be nice, but that probably won't hit for a while unless they start out with frames, which is unlikely...
Your thoughts on user toolsets?
