LEFT ANALOG STICKS (L3) weaken over time, mine hardly works now. Battlefield 4 has the option to[b] tap up twice on the left analog stick to sprint[/b]. This isn't an either/or option, it's just always present. If you like clicking L3 to sprint keep doing it, but my analog stick barely works now! Please Bungie! Add this option! It'll save us the money in buying another controller! Everybody support this please! Thank you!
