The only problem with this would probably be the final boss, where you're forced to use everybody. Basically the party splits into three, two parties take out two forms and Adol takes out the final one alone, so that would be the only problem (unless you know how to hack it so that Adol enters those other two fights).
Um what whole weakness system kinda goes to @#@# to. this game has three attacking types PIece slash and Crush. Adol by default has slash and much later on about half way can change his weapon to one of the other two types. but the problem is a lot of enemies come at you in groups and your gonna have to switch every single time. its just not worth the trouble. unless someone hacked his endgame sword (which is a slash sword that is super effective against any of the three types) and maybe pasted it with different damage outputs over the other swords. but using a normal playthrough i would highly recemend against it.
either way its kinda fun with party members you can actaully have dogi with you :)
