Pyke vs. Zed
I noticed that with Pyke your engage tools (W move speed camo + E dash) are also your disengage tools. So if you blow all your shit going in then you have no escapes... it makes an interesting choice on when to use abilities.
But with a champion like Zed you can blow all your engage tools and still be perfectly safe to escape. You are always safe to disengage and there's less risk or choice on when to use abilities because there's not much downside to going all in... just press R again and escape.
I prefer the former... I think it's a better design.
