Most sly players use he because they know hes op and solemnly wanna win, and not have fun. Sly players or the character dont sux its the majority of online ppl that do. My 2 cents
But he's not. I use him because he is the reason I got into Playstation and I enjoy every one of his game. I have only found 1 decent Sly player, but that could be me hallucinating because he was partnered with a pro FP.
I'm a decent Sly player and I don't play him because he's "OP". I play him because I feel cool playing someone that agile and tricky.
What people don't understand is Sly is supposed to be annoying. His agility makes it easy to either tech chase, or hit and avoid you. The whole no-blocking thing really does offset his move set though. And just because he is annoying, doesn't mean he is OP. If anyone wants to open this bag of worms, I am willing to lay down some knowledge about Sly.
And I could swear his level 1 got nerfed during one of the updates. It seems like his level 1 is more prone to stopping once it gets to the first person.
See, the thing about his level 1 is that, while I ALWAYS keep my eyes on Sly, he always gets one or both of the other players; no matter how defensively I play, the other two cost me the match for their excessive deaths.
And interrupting Sly's 1 is not possible
So long as you go positive, why care if the Sly kills other people?
