The reason Blaanceblade if so weak is because it just doesnt go to Balance, but to all schools. However, I'm not saying a 30 percent Blaanceblade ( not dragon blade) wouldn't be a good idea.
Ice deserves the better blade anyway. they have the weakest attacks in the game, and storm is the strongest. Balance gets through it all quite well. I dislike the idea. I'm sorry. It just isnt fitting. And yes, have you ever heard of Dragonblade? Also, this should ring a bell. TREASURE CARDS
