Yeah, the unbalanced aspect is pretty apparent. I've already gotten him to Super Elite, and I can see the problem with Spell Disaster. Even larger characters have the potential to get 1-shot by spell disaster, due to the fact that at close range it's possible to get caught by 2-3 orbs. What it should do is place a glyph on the ground that lingers at the spot it was cast, and maybe has a similar effect to jinx/time snare. Possibly even add a stun if an enemy is caught in the AOE when it's cast. It's extraordinarily effective under the right circumstances. My friend and I were playing around after I unlocked him, and by using Zeelixir + Sprint Tackle, immediately followed by Spell Disaster + Shield Dummy, we could clear objectives with 4+ players with just the two of us. We'd be able to easily pick off any survivors with the combined firepower of Co-Star and the Football Cannon.
