I think it's reasonable to be able to loot one random piece of equipped gear from a defeated player in PvP. That way there is risk and reward associated with the engagement, without breaking the spirit of the defeated player. Remember, a successful game has many players, not just the few who haven't been robbed by the best players. And the care bears should be allowed to play without "involuntary PvP" making them run back home to Merlin Ambrose. A really good game should have aspects that keep the casual gamer interested, but able to see and appreciate the glory of the hardcore gamers (be they gladiators or siege warriors).
