I was playing Dota 2's Warlock and a spell of his gave me an idea for the Summoners Tri-Disaster. Warlock's Spell is this, "Binds several enemy units together, causing 25% of the damage dealt to one of them to be felt by the others." The ability has a limit of up to 6 targets, but for this game, lets give it the same amount as Bane

Whats if Tri-Disaster did this and Bane prioritized enemies affected by it?
Remove the bind, and give Summoner something more practical, because the damn bind never works anyway.

What do you think? Good idea or a bad one? Completely over the top? Or a good addition?
