because it is easier to ignore fighters and monks and let players run all caster partieswhy don't you rein them in via houserule? It's hella easy: just say they can't (and that no arcane caster can) cast spells while in armour. Boom - now they have to choose before each combat whether they want to act as a caster or a warrior - can't do both at once.
OR
house rule a bunch of things and run a no caster party.
