Yeah but you don't have to junction the most powerful magicks if you don't want to. Also I was thinking that when you get your str stat to 255 that junctioning to the limit strength will increase it further because it divides the damage up and Lionheart doesn't always do 9999damage per hit. I never had to use magic either but sometimes it's nice to have such freedom to do whatever you want during battle.
Also: What is this "Crisis Level" system? I never heard of that.
Also also: If it is too confusing for beginners (I never thought about the beginners) then maybe the choice of "Expert Junction System" at the start of the game.
