Are those complaining just complaining because they're getting smoked?
Too used to playing slow FPS titles instead of this?
Also, to those saying the movement is COD. You clearly haven't played COD in a long long time.
Cant speak for everyone but I'm doing ok , not getting smoked as you put it. I'm not high on the scoreboard but not low either, I play exclusively as a medic though so my focus is generally on reviving rather than killing anyway.
As some others have said, its an ok game but just "ok", nothing more. Its not the best BF game (or even one of the better ones, which are imo BF1942, BFBC2, BF3 and BF4) but its not the worst either...its just middle of the road.
I'm definitely more used (now) to slower paced shooters, like Tarkov, HLL, Hunt Showdown, Arc Raiders etc, so I do have recency bias of preferring a more thoughtful, tactical approach to gunfights than running and gunning.
In summary, I find BF6 to be alright..just alright, a 6 or 7 out of 10 game.
