if you play with the weak characters though you have to use the strongest class for that character though unless they'll die... solo ofc... if they get support then its w/e but throughout the battlefield i separate my characters so they can solo and attack from all angels. and i want to be able to choose the classes i want...
for example...
Knoll (dark mage) sucks... and if you make him a summoner, hes worse. so if you want to use knoll you have to make him a druid or he wont survive.
