hmmm... while my 2 cents would have to be...
mercs should have to come into the forums and state that while be joining the war. then the alliance leader would have to aknowlage them and state that they agree to let them join there side. Then there should be a 24 hour period in witch the merc would have to wait so that the opposing alliance can aknowlage there new threat. when the 24 hours is up then the damage done by or agenist would count to the TD. when the merc wishes to leave the war, he then would state in the the forums, then they would have a 48 hour period in witch thay would be forced to stay in the war because of the whole france VS mexico thing
with my line of thought pattern i'd say that the wars should be limited to a max of 2 active mercs per side tops with a maximum of 10 mercs highered per war...
if some one is to call a player verses alliance war then that player must be at lest 1/2 the size of the strongest player of that alliance (stairs at ahsan) this would then prevent any player that is under 10k points from calling a war and highering mercs to do 99% of the dirty work.
and i'm sure i could think of more but i'm to to lazy at the moment XD
