Stamina is too low too slow

The stamina system in the game is horrible, I barley have enough stamina to sprint for 4 seconds, and when you’re out you need to release the gear in order for it to replenish, which takes almost the same time it takes to spend it. I just don’t understand why, it’s not like running breaks the game or anything, especially with the lack of mobility options this season, and I know you can have unlimited stamina with slap juice and run n gun smg but the base system should also be improved, either make it so that stamina is unlimited and maybe reduce the speed, or make it replenish more quickly and last longer
