- You're on a clothie that you know you can kill with an AR. - The person you're on isn't getting any healing (i.e. your partner is CCing the healer on the other team). - At least two other players are standing together so you can pop BF and AR.
Oh and one more thing, ive been wanting to try a healer for 2v2. but ive been hesitant seeing how my damage isnt that great. or at least it doesnt seem that great lol
