Currently prone to sprint animation doesn't match the actions players do. (See dropshotting clip from decimals video)
The player is able to go at running speed while still in the process of getting up from proning, essentially causing players actions to not match (Fast speed while model is busy getting up from the ground.
One way battlefield 4 for example addressed this is by not allowing you to move when prone to sprinting.
Battlefield 2042 did this by allowing slower movement in the process of getting up from proning
Personally i find BF4 to be too stiff with it's prone to sprint, so going about it like BF2042 did might be better.
