that was the intention. one shot grenades when you are near one of your teammates that are in they're super. but I can see the concern. perhaps a 33% damage increase would be better? And I fail to see how the sanctuaries would be OP? If used correctly then yes, but one must use proper timing no? you could use them to claim control points, however sun breakers can do the opposite and keep you off a control point with sunspots no? or control choke-points? I had the idea that they could be used to move up the line of combat.
