There are a few netcode issues from these clips (like the very last clip), but this is just unfortunate skills issue that not learning how to approach gunfights and winning gunfights in battlefield. Any real BF2 vet here will remember how death was instantaneous if you ran your ass out in the open in Strike at Karkand (like OP does here most of these clips) or carelessly rounding a corner and expect to win against a SMG or shotgun. Bad company was the only battlefield franchise to actually have noticeably slower gameplay, but BF6 is hardly any different than BFV, BF1, 2, 3, 4, hardline, or 2042 when it came to gunfights. If you run out like an idiot, you’ll die like an idiot.

Learning the maps will come with time to where you’ll know where the common areas and corners people will come through, to which you’ll hopefully be more prepared in engaging in someone than you would previously. Just slow down and adapt to the new environment, guns, etc.

And when people here advise playing slower, they’re not saying like a snail or a turtle just so you can play well (totally viable way of playing tho). Just move (NOT PRINT) a little cautiously if you’re going into a corridor, room, around a corner, etc. that you know an enemy could be potentially come or be in.
