Pyke can be the stepping stone for new QoL changes
It's simple. When looking at Pyke and how he works, many of his abilities seem very similar to some we already have in game.
Pyke W and Twitch Q, Pyke R and Cho'Gath R/Urgot R, being the main two that I see.
The QoL changes that I say could exist are very simple.
When Pyke uses his W, any enemy nearby are able to tell when he is around by shark fins circling around them. A simple change to Twitch that would improve his "counter play", since I know Riot love this phrase, would be to add a similar effect to enemies nearby when Twitch is sneaking around in his Q. We already have the effect on one of the other users of Camouflage, Rengar.
Now, with Pyke R and Cho'Gath/Urgot R, Pyke has an indicator on enemy health that lets him know exactly how low he needs to get them before he can execute them with his Ultimate. I understand that Cho'Gath and Urgot already have similar effects going on when they in range to get there Executions, but they're not as clear as how Pyke's are. A simple QoL change to the both of them, would be to just add that little blip in an enemies health bar, to show them exactly how far they need to be down to get Executed.
Those are the two that I can think of off the top of my head. Please, if anyone else notices similarities between Pyke's kit and other champions abilities, reply and give an example of how champions could be improved with the existence of Pyke.
