For example
Class interactions (Rock,Paper,Scissors)
archers vs archers = skill matchup
archers vs ua/mc = archer ( line of sight dodging the arrows makes it a skill matchup)
ua/mc vs ua/mc = skill matchup
beserker(b12 axe) vs beserker = skill matchup
beserker vs archer = beserker (some sort of buff needed here - like "beserker rage" which inspires fear in the archer decreasing his chance to hit or something)
beserker vs ua/mc = ua/mc (possible skill matchup)
Possible armor ideas
Archers can wear up to full leather - Full leather armor = 150% stamina of full tank armor
Beserkers can wear up to full chainmail armor - Full chainmail armor = 125% stamina of full tank armor
Ua/MC tanks can't wear leather armor once they have equipped other higher tier armor (anti ctc chest option to keep the armor lines pure) - 100% normal stamina.
