Reward for finnishing a map.

How about an accolade system?

Examples:
Most ranged kills (Archers and Skirms)
Most melee kills (Slashers)
Most attacks blocked (Shielders)
Most heals (Healers)

And of course, only one player can aquire each accolade, so you really gotta work for it!

Just an idea.

EDIT: Now that I think about it, the accolade for most attacks blocked COULD be a problem if there are multiple shielders..
