would be awesome to have everyone be able to hire 5 mercs(or slaves) no matter what charisma is. (lulz, huge populated wars)
but if seriosly... i hate and love mercs, well they're fun to play with, but they're deadly annoyning too, if for example abused in combat. (hint: dual logs, bug abusing, waiting on WM for noobs to enter town to get blowed up by mercs, etc)
