Sylas top be like...
######I made dis. I'm very proud of it. Spent like 25 minutes finding the pictures, fonts and stuff and 2-3 tacking them on each other in paint.
I like Sylas - A LOT -. I've been maining him since his release and just got Mastery 5 after winning a match with the build you see above.
He is REALLY hard to learn, but i am concerned that once people figure him out he'll be the second coming of Ekko. He has less mobility and is generally a lot less safe, but he has OH SO MUCH MORE utility in the hands of a half-decent player - even someone like myself can climb with him!
I can't really tell if he's in need of nerfs because he's so god damn weak compared to similar champions. Where other mages can typically 100-0 someone with a full combo once they finish their luden's echo, if Sylas gets luden's he can perhaps do 40-50% of a marksman's max health.
But playing him makes me feel like i used to feel back in season 4 and 5. Like a true top laner. I'm actually a proper front liner and initiator for my team again.
I'm actually having fun playing League of Legends.
I feel like would be a solid build as well...maybe 
instead of 
that face-tanked an entire Rek'Sai rotation and took a grand total of 10% of his health as damage before two-shotting me with a sourspot Q and E.
as the only AP on an otherwise full AD team; our team was a mix of true, magic, and AD. He had the second most damage dealt in the game after my 300+AP transcendence itemset, and around twice as much damage soaked and mitigated as the next highest.
