Suggestion: How to make Support feel like how to it did in BF3&BF4
As most players probably have noticed, the Support class doesn't feel like how you expect it to feel.
The solution to it might be to make it more akin to the feeling it had back in Battlefield 3 and 4. And it can be done fairly easily through the attachments and weapon control.
To make it feel right: Heavily promote the use of bracing and particularly bipods for VASTLY better accuracy, making the recoil near nothing (apart from first shot recoil) when deployed on a bipod, and very little spread over sustained fire. Obviously allow for building the attachments for certain ones around unbraced use (like the DRS/416). And also reduce the attachment cost of full capacity magazines for them but increase the cost of the weapon control attachments like grips and muzzle breaks&compensators.
This would truly make the class a support class. Once the class feels right, then the class gadgets can be addressed.
