I think we all know it... Scorch is op. Now I can make a long drawn out post about it (and I really want to) but not many people will see it. So I'll just lost his opness.
1.) His potential damage is honestly retarded. I lose brain when a fully Charged can just one shot me because he ran around like an idiot putting people on fire
2.) He's the most mobile character. Not only can he one shot you, you can't run from him or chase him. He has two dashes, both which do a lot of damage, build up his blaze and one can clear CC.
That's it his other two abilities are pretty ****. He only needs his three abilities and he'll still be a good character.
