The REVIVR is fine as it is. But REVIVR has a pretty poor quick ability effect.
I have found two thing about this ability gun :
If you want to cancel a shot you can switch weapon, which is slow. Cancelling is not really useful (since you lose the charge anyway), but shooting a red beam reveal you position quite well to the enemy.
When you use the quick ability button when charging, the shot is fired, and you need release the fire button and to click and hold your fire button again to charge it, which is clunky.
I could see some useful changes about the quick ability :
- having the quick ability button just cancelling the shot(without any charge recovery of course), which is a pretty harmless change
- having the quick ability button fire the shot but also engage a new charge if the fire button is already pressed, improving it’s real firerate and making it even more special
