Do not give players an indicator as to when they can execute a target. No one else gets an execution indicator, and it lowers the skill floor / ceiling. This makes the champion a bit more boring IMO, and helps bad Pykes avoid from wasting R. PLEASE do not keep this.
Find a way to keep Pyke in the Support role, or he'll likely end up gutted / a balance catastrophe.
@1. 
both have indicators for R. Eves is just for damage boost, Chos is for kills. Also 
has a indicator for when he has dealt enough damage for his R has enough damage to kill.
Literally every champion with an execute ultimate has some sort of indicator ( 
), the only notable exception being Darius. But I do agree that having no indicator would make the champion harder and create more skill expression.
The second suggestion is good but it most likely won't happen. Let's keep our fingers crossed.
