Some ideas that could fix Lime and make him usable. I don't hate him, I want to like him. But he's absolutely useless.
Higher HP: His big and clearly meant to be a tank of sorts. But his HP is pitiful. A very simple string of combos can wreck him. This makes Lime free damage to you.
Spread out minions: They're too close, meaning they all get taken out too fast.
Give the minions higher HP: I understand that they're just, little tiny boogers, but oh my God they're useless. They need just slightly more HP.
Don't stop on hit: Lime is a big, gelatinous, blob. Why doesn't he bounce. He should bounce.
Change his combo into creating a trap: Instead of giving him a homing shot, his combo could be a big splatter that catches enemy Capsulemon.
