He gets countered by so many characters... He can be decent in 1v1 depending on the matchup, decent in 2v2 IF he has the right partner (BD/ST is a really really good team!), and mediocre at best in FFA.
As a ST main I am offended. I WANT MY LEVEL 3 back to its normal time!!
Also I use 90% of his moves (Mines are meant to be left as a set up/trap not for spamming) I played against ST's that think they can just spam the shotgun and mines. They are so easy to beat. (Even fought a team doing this)
As for what legalize said kratos does need some cooldown that's plain to see I'm not dening that. And kingmtj if you mean sweet tooth and use all his moves than you should see how little this will affect you. And like I stated thet SHOULD make his level 3 a bit easier to get but there is no need for a kc for something you get in 4 HITS effective or not.
Pro tip: Avoid the mines. Stall your wakeup, and change things up; he's obviously predicting (and gambling) on where you're rising, stop being predictable, and he shouldn't be able to touch you. Sweet Tooth's moveset in overall lacking, he needs his mine in order to control space, since most characters can rip him apart otherwise. Just be mindful of it, and it shouldn't be much of an issue, I rarely land on a Sweet Tooth mine when I'm facing him, and they're easy to destroy quickly. Adding cooldown to his mine would kill him, and he has possibly the easiest kill confirm to avoid in the game.
Sweet Tooth is quite low tier, and not great for high level play. He has a couple good matchups, but the majority of the cast are a bad match up for him.
