I would to see the return of this theme in a guild. Previously this was called
Dog Fighters guild, and I enjyed that guild. a Mercenary guild would be a good
fit if the military background is being initiated as previously mentioned.
Also they could e a tanking option for nomads as most Mercenaryare nomadic
going were the money is.

As rep system for them I would think it could be based on how muhc money they
collect from the foallen mobs they kill. The money they colect could then be
saced to the guild or something along those lines. This would help clean up
the piles of mowgles the mobs leave behind.
Just a thought..
