Sylas' Kit is OVERLOADED and if you can't even slightly agree, you're a Riot slave.

has one of the most overloaded kits in the game next to the reworked . Honestly isn't even that cray cray, now that they took away the bonus shield damage.

He has a slow, an execute style gap closer another gap closer that stuns and knocks up

a dash that shields him an obnoxious fucking heal (who do you know besides a support that has a shield AND a heal???) cough cough You can count , but he needs to time his ultimate correctly to get a decent heal and his shield is very conditional. You can also count but his lack of mobility makes up for the shield and the heal.

an innate aoe sheen and a stupid ult that lets him cast an ultimate at least twice in a relatively long team fight The way his ultimate cool downs work make him very effective in picks and less effective in lane

So essentially you have an extremely unpredictable (his ultimate) hyper mobile assassin with too many support like qualities. Fun to play against. Maybe you can deal with him in lane phase but come team fights it seems like total bullshit.
