The weapon TTK balancing changes in this playtest are far too arbitrary.
"I hope you give some serious thought to the proposed changes regarding weapon fire rates. For players, fire rate is absolutely crucial to a gun’s feel—most of us simply won't accept these kinds of adjustments. That said, the issue of overly fast TTK (Time to Kill) is indeed a pressing one.
But I have to ask: Don't you think that binding damage directly to ammunition type ties your hands when it comes to weapon balancing? Please, stop being so fixated on what caliber a gun uses in real life. This approach is effectively stifling the unique identity of every weapon.
Do the actual work of balancing the guns. Starting over isn't something to be ashamed of. Redesign the TTK for every weapon from the ground up. Damage should not be dictated by caliber. Leave realism where it belongs—in the real world. This is a game. This is Battlefield!"
