>>6404370SRW has balance in a "Hey, let's make all units powerful and be able to simply attack to the enemy spamming seishin commands to win". It's not that there are many different classes in SRW to begin with. There are powerful units being to be able to attack from close, from afar, being able to cast amazing support seishin on themselves to get INVINCIBLE against any enemy in the game, all together... Balanced you say?
It's not like in other SRPGs where you have tanks, several degrees of damage dealers, swift attackers, healers, supporters, debuffers, long range moving units... all of them with clear disavantages and weaknesses to particular weapons and classes.
