Extra xp or gold for anything is a TERRIBLE idea. It breaks the foundation of "team" playing.
Yea so someone can do the most damage to doors and get xp, then they will just farm doors, same with others.
If you give xp for anything but ticks, people will start abusing it by just farming.
crpg is fine the way it is, incourages teamwork and helping eachother, we're already are kill/xp/gold hungry bastards, why make it worse?
