It says you can only choose two kits as a donor when you try and switch your kit while waiting, but I think that isn't fair. Even if you make a mistake while choosing kits, you can't switch to the kit you want. Eg, I want swordsman lvl 3, but I click enchanter by mistake. What now? Not fair, is it? Maybe you should add a button that says unselect current kit(s), so,if you make a mistake, you can change the kit to which kit you want.
