Is there a chance he could have the ability to reactivate his ult to detonate it before it's expiration? I feel overall he's in a pretty good spot but I've noticed that there are many situations where waiting for the detonation to kill someone can result in alot of extra damage being taken or sometimes death as a consequence for what is often an impending overkill.
I don't think it's the most urgent thing but would be a WONDERFUL quality of life change.
Edit: I don't have intentions of the switching to the R's shadows being removed. I figure there could be a modifier key or something. The idea is the mechanic, not necessarily the execution.
One point of the delayed detonation is that it allows us to amp up Zed's single target damage to ridiculous levels while still retaining counterplay -- Zed engages, "condemns" his opponent to death, and then the game becomes Zed trying to stay alive while his "already dead" opponent tries to exact vengeance.
