For the XP loss for resetting skills, first, could we have a confirmation choice, so if we do the wrong command on the wcsmenu we don't lose XP for accidents?

Second, if we have it flat "next X kills" it's going to be more painful to lower leveled players than higher, since they get more XP per kill, on average. Perhaps something like "Next X kills, where X is your level". One problem I see no matter what you do, is going to be the storing of this information. If they switch race, you're either going to be letting them lose XP from another race, or have to store those variables somewhere. Dealing with crashes, disconnects, and just map changes, there is the ability of a lot of these things needing to be stored. Not sure if this will be enough to make a difference, but throwing this out there anyway.
