We all know the rule; "The longer the execution, the more health you get back." Its the 2nd thing I look for when picking the executions I want for my heroes, next to how good it looks.
The thing I feel like would be really useful for players, and something I can't imagine would be too much to ask for in a future update is, when viewing these executions in the preview menu, include the exact moment that execution gives the player health.
Already a few times I remember wanting executions because they looked great and because I thought that health grant was sooner than it actually was (which is reasonable to assume when some of the executions dont actually finalize the kill even after disembowelment or impaling) and been confused, within reason as to why.
I feel like this sort of feature would be convenient for players wanting to stylize their heroes with a splash of practicality.
