[2020] I don’t know how to enjoy this game.

I have over 100 hours in this game. For probably 2 of them I have had fun. I only have that many hours because I play with my friend. But it feels like every raid I go into I die. I never get out with loot and I’m constantly just following my friend around not doing anything. If we get into a fire fight I’m useless. I never spot enemy’s first. Constantly he will point out things that I never see. Why do I suck and why can’t I have fun? What am I doing wrong?
