have the tams on each corner and the buff time is the time they get before the other team runs to you and starts the fight...
both teams should be appart but not far enough to allow minimum buffing, not the hour long ones... just out of sight range, this should give time to cast arround 3 spells not counting the auto quikened builds...
well
the fight itself would be nice to have an area that looks like a colliseum... where people can watch the fight including non participants and lower levels, and not wait in avendell while fight is somewhere else...
if not somewhere like the bandit hide out, by the bend near NS people could watch from the side cliffs and the battle in the middle...
hell we could even charge 5 GP entrance fee to watch the fights
