He was a mixed bag before the combat rebalance. For an at-will, he has a resolve heal. For his cooldowns, there's an aoe tease and a hybrid stance thing which does aoe fire damage initially, and afterwards deals tease damage to enemies that hit him and boosts his resistances while dealing a small amount of damage to him each turn. His encounter power is big for a tease comp, as it deals a little bit of tease damage but amplifies the damage of all resolve attacks by 50% for 3 turns, while his ultimate is straight up just a really strong tease with a one-turn stun.
After the combat rebalance, he's also a mixed bag. Slightly better for a general team, but his tease damage is generally pretty low. His sexiness is high enough that he can do good teases, but it feels like his tease damage simply can not hold up. Like, his ultimate is a Tease attack, and you'd think it would be strong, but in a quick test against Grettel (high armor, decent warding, low focus), Etheryn's Iceburst Arrow (note that this is at level 6, pre-winter city), which I think is a mixture of physical and magic damage, does 158 total damage to her, while Quint's ultimate only dealt 128 damage. A cooldown power hits harder than Quint's ult, despite the target being weak to tease damage and much stronger against physical and magic damage. For its low damage, Quint's ultimate skill does not provide enough utility to be useful.
Ignoring that, just looking at damage with other attacks against the Wyvern. His basic tease (and allure, which is equivalent to a basic tease) hits grettel for 41 damage. Etheryn's basic attack, without use of her at-will (remember, this is without the Winter City buff) deals 52.
Honestly, overall, Quint has pretty bad damage. He still works as an accelerator for lust teams, but tease damage feels way weaker than it used to be. That said, his stance, Firewalk, still deals some pretty great aoe damage on activation, and he does have a heal. Though, unfortunately, his heal is a flat amount, rather than a percentage heal, which feels rather underwhelming. He's supposed to be a support, I think, but the composition he best supported isn't anywhere near as good as it was, so his usefulness overall is worse. Still, I'm decently positive on him, purely because Firewalk is just really good.
That would be silly. It would only belong in Silly Mode, if it were added. Also you can just imagine that your Champ is doing it, since this game is text-based and lets your mind picture things.
