does a flower count as a weapon? if not, monks should get their own bracket since almost nobody else takes unarmed.
could have BAB 1, 2, and 3 brackets (then by level range) so you don't have fighters and casters battling it out.
be great if the flowers for the event did have special properties...roses have extra piercing damage, tulips do fire damage, daisies have a daze effect...
Andrew will request a pansy *grin*
