There is no specific rule against autolooting. However, it IS NOT okay to
loot someone else's kill. If you set up a trigger to do this, PLEASE set
it up to where it says "You receive <amount> experience" or something
similar, NOT to "<mob> is DEAD That way it will only trigger on YOUR
kills, not on other people's.
It's also a good idea to turn this off when you are in a form, because the
leader is likely to get angry if you automatically loot equipment he or
she planned to loot.
