Re: Teammates quit almost every game.
No I mean fight when he fights. Most people will stay in the game, at least until executed, if they see that you are fighting the same guys that he died to. Nothing more triggering than when you fight and do well, maybe knock two enemies solo and dies to the third and you think that the third remaining enemy will be a piece of cake for your two randoms. But then you find yourself being slowly executed with your two randoms nowhere to be found and when you become a loot box and goes to spectator mode, you find your teammate sitting like scared rabbits in some building with 0 dmg dealt, full purple armor and peaking with a Sentinel, i.e have done NOTHING to help you in that fight.
But like I said, this is only a tip IF you want your teammates to stay. There are definitely randoms that aren't worth sacrificing your personal advantages just to keep around, i.e those randoms that cant do 300 damage after 4 squad wipes etc. I think you are experienced enough to also immediately spot which randoms are worth playing with as a team and which randoms arent.
