yes, indeed.......there is a difference between a BUG....and an IMBALANCE

a BUG is totally unintentional...an error

an IMBALANCE is something that was INTENDED to be there, but perhaps not in the exact form it turned out to be

blizzard never intended people to be able to get gobs of money by deleting farms

they DID intend to let people make hunts, and ghouls, and all that (and lots of them, if they desired)

incidentally, there are ways to stop mass hunts.....mass ghouls....shamens+witch doctors......just dont let your opponent make them! they are "massed" it does take a few minutes

level doesnt mean much until you get to a pretty high one.....just about anyone could get to 14 or so, on easy (er, east) or west, or europe or asia

ps.
especially as humans (which you seem to use as torahman and endersgamer (both level 8)) you should have little problem with an orc, if you do it right
