Protect your healer.
Loving the game so far, I play Support which alone brings it troubles, what with being the main focus of attention as soon as I am spotted. Just had a few games, and while while I am healing ( I play zero cool I know squishy ) I am not getting the help I need to keep you guys alive. So if you see your support player getting focused on, please go help them out, its a win win really, You keep the support alive they keep you alive.
@SilentParasite Yea zero is the most dependent on help from teammates so if they never help you then either of the other two would be better choices
