Then This warrior used slow movement speed because of his armor, wasted AP to switch weapons. Just have to balance by increase AP cost of weapon switching and there you go.
Not fan of Loremaster giving you info about memorized skills, it's too much of an advantage, but is ok for other info like armor/hp.
He doesn't have to wear heavy plate. He can disguise as all wizards or even naked if he wants to avoid movement penalty.
Not sure why character sheet giving you info about memorized skills would be consider an unfair advantage. You can make full inspections even with characters that don't have points in loremaster since it's not required in Arena. Also, with the current preset roster everyone already knows everyone's memorized skills. All this does is to make sure things stay that way even with customized characters.

But Sideboard like MTG is an interesting idea indeed. I was thinking best 2 out of 3 for a tournament setting. If you lose your previous match you get the chance to swap out your entire party before the next match. A limited swap like a sideboard should encourage more well-rounded party setup though.
