 Let us say it is non-conventional. 
 What I proposed goes into a 1v1 arena type later in the roleplay, being preceded by team based pvp.
 Combat encounters can start in different ways. An ambush, or groups walking into each other. (for the first half)
 Then the fighters get introduced and then walk into the ring of the coliseum, beginning the fight. (for the second half)
