Good concept! Might be nice for a couple of the low armor bots to have a little regenerative capability. the Cheetah for one, being able to duck out of fire and recover 10% of srarting health over 5-8 seconds would definitely add to its allure. I like it but its so weak ifyou cant strike and fade your survivability is quite short.
Like this idea and the similarities between cover and help are pretty mush the same get over here so heal could easily take up that help place without the need for to many options
I also want to see this tab moved to the topright of screen. Not a fan of having an interactive tab right next the fire button. The kill dialogue could be moved to bottom left since it has no interaction with touch it wont be an issue near the analog stick
