Sylas seems like a better version of Ekko

I've played both a lot. Sylas is just better. Better sustained damage, more frequent healing which allows him to last longer in fights and do more damage. He has fewer mana problems and has more CC than Ekko. Yes, Ekko can potentially CC multiple people with W, but it can be hard to pull off. Ekko can do more AOE damage, but again, difficult to pull off. Sylas has reliable and consistent damage. Ekko can burst harder in a short period of time when fed, but Sylas can do the same when he's even. And yes, Sylas relies on the enemy ultimates for his ultimate, but there are rarely games where all of the other team's ults are useless. This Dark Seal nerf on the PBE will hit Ekko pretty hard because many Ekko players get double dark seals on their first back which will cause him to lose 10 AP overall. I'm not saying that Ekko is weak. I'm just saying that there are better melee AP assassins that outclass him.

Sorry that this turned into a rant. Just a little frustrated. I understand if this doesn't convince you about anything.
