As someone who's been playing this game since 2018, I genuinely haven't seen a more broken and brain dead brawler than him. For a few reasons.
His attack is absolutely friken stupid simple, just button spam and that's it. Especially the explosion at the third one, the fact that it chains forever is just stupid
His super is also absolutely stupid! A big ass area that you can't leave and takes at least two attacks to escape, knock back if you hit the walls and he can just spam his attack, keep people close and infinite explosion then to death.
I've seen his take out entire teams by himself, teams of closer ranged brawlers. There have been broken brawlers before, but this is just insane.
Using him is stupid easy and requires no skill at all, that's my biggest issue. Have a brawler who's strong when you play him right, this guy? Hell nah, just spam spam spam, super you can't escape, spam again and you've lost.
Don't know why supercell are taking their sweet sweeeeet time fixing this guy, sirius got a pretty good nerd pretty damn quick, and actually I think I know why he isn't getting nerfed, cuz the only way to get him is by playing the ticket event, spending gems or just money. But that leads to this whole time he's exclusive in those places to be a really horrible time for the people who don't have him.
