All they needed to do is chill on the particle effects. That's what's making it hard to see at times.
Enemies glow FFS, so not sure how people were having issues seeing them! In dark corners, sure, but that's the point? Sometimes when someone is prone, they look dead the way they're laying. That's frustrating to me, but that's an animation or spotting issue with the game.
Also, people don't seem to spot enemies in BF anymore. It puts a diamond above their head, which is a staple of the franchise. Can't decide if you're looking at an enemy or not? Spot them! It also helps your team greatly.
I've come to the conclusion that BF players are mostly bots. They truly are terrible at the basic mechanics of FPS games, like positioning, or any sort of strategy with defending points. Seems like the average BF player just relies on their pure reaction time above all else.
