Ace now has to cook his S.E.L.M.A. throwables for two seconds for each additional breach stripe as indicated by the new crosshair (up to a maximum of 3 stripes).
This change allows him to keep is maximal breach potential and utility clear while reducing his ability to overwhelm defenders through the sheer volume of simultaneous triple breaches that he previously had when spamming all his charges on a wall.

Reducing his magazine capacity by 5 brings his firepower closer to the other hardbreachers like Thermite, Hibana and Maverick.
