For me being an offensive player and like big damaging spell cards, I leave out balance. Myth is ok but I don't think I'm going to keep it when it get's to Avalon because I feel the multi attack spell cards alone are not strong enough for a one shot spell until level 100 for Mystic Colossus. Most of the bosses are immune to stun so I feel Medusa and Basilisk are almost useless for that purpose. Don't get me wrong, these schools are ok for what they are but to me they're not efficient enough in damage wise. By the time you get multiple enhancements up, you'll be defeated and healing yourself only works for so lone if you go solo and not enough crowns to buy henchmen.
