Gunplay Feedback of the Most Players isnt Worthy

Hello dear Battlefield players.

I have a stomach ache ... because a lot of players don't know what they're talking about. The gunplay is fine for the most part. Just learn to play Battlefield.
You have to understand how the weapons work. Only then can you give qualitative feedback.
But most of the feedback I see here is just false truth and a lot of "mimimi" 
So please! Learn the mechanics. Test, and then give real feedback and stop telling lies
