@aisthebestletter I don't think it's anything on your end. I also don't think it's just one thing. So many things can be the reason why.. Server congestion at the wrong time. Just bad luck in the game, things like they have purple armor, you have white. They have the currently OP gun, you don't. They have favorable positioning, you don't. Occasionally it's audio issues, I don't hear them but they can hear us.
Lots can play into it. I have rounds in which I post huge numbers, I also have entire nights in which I struggle.
You might also be bouncing between different skill level lobbies. The higher skill lobbies are typically premades and they do things like focus fire.
I've seen even "pro-gamers" have multiple bad rounds. It's just the nature of a BR game. This is not like a strategy game in which you can dominate/win almost every match you play.
The other part that plays into it for me is the constant nerf/buff. I get good with what's OP it then changes.. Now I have to learn to use a different gun or legend. Some players adapt faster than others. I'm a tad slow on the adapting.
