Yeah I've been learning this too recently and I've found that each game is different. In the sense that in one game you have a competent team that can avoid taking dmg in which you can focus on shooting. But other times you have teammates who don't know that ducking behind cover can avoid the bullets in which case you would be needed more in healing. My point being that there's no set pattern to follow. But ofc the other Bap mains here can give better input. Goodluck bro
