I’m at level 25 so I’ve been playing quite a bit. I find that it doesn’t really matter if I win or lose, if I’m the best player or the worst, if I gain a ton of medals or only one. I always (generally) get the same amount of Req points. In the 650-850 range on Arena and somewhere around double that in Warzone. I’ve absolutely sucked in games before with 2 kills and 10+ deaths. I’ve also owned everyone on maps before. So neither how you perform, nor if you win makes any difference when it comes to the amount of Req points you get. It is generally always the same.
Why was the game created this way? Seems pointless to me. Just grind the game, who cares how you perform! Almost like a paycheck instead of working on commission.
