I haven't and won't. I have friends who play controller on PC and console. I switched over to PC MNK 8 years ago, don't have a desire to. From seeing their stats compared to mine, I think most things in BF6 are in favor of MNK players.
I really don't think AA is egregious in BF6, especially when compared to CoD, Fortnite, Halo Infinite, etc. It's actually somewhat balanced, minus the recoil difference (MNK has almost double the recoil, AA not engaged just shooting at a wall). That's a serious problem.
Overall, I think they have balanced the inputs better than almost every other modern crossplay shooter. I just don't understand the argument that people on MNK losing out gunfights are "bad". Controller is factually easier to use. Let's just be intellectually honest and unbiased. I don't care what input you use, just don't sit there and defend it like it's a personal attack when a MNK player doesn't appreciate the strength of AA in general, not just BF6. It's a valid argument.
I had pretty good stats while playing Support and actually playing my role. 2.7KD first weekend, 3KD second weekend. Being positioned well, imo, is the biggest factor in playing well along coordinating with your team/squad (it's Battlefield at the end of the day, not CoD, which is a huge positive to me).
