I think fire should have the blade and storm should have trap because think about it fire has DOTs. it damage over time. That means most of our spells are useless for backdraft. Then storm should have the trap cause they dont have many DOTs. What do you think? I think it should be.
If you don't like your trap spell it doesn't mean you need to ruin other school spells, supercharge should stay as it is. Just ask to have blade instead of trap.
