I max out spell drawing whenever I see one worth it to junction since I'm pretty much a power gamer so I cant not do it. If you dont want to do it then dont. You could just leave Zell at low hp and kill everything with his limit first round by doing is o-x, ^ v, o-x, ^ v, etc till his timer runs out, which makes things easy mode too despite what you have junctioned. I got 4-5 hits per sec off his timer doing this, which is why he's the best chara in the game.
