So, whenever we want to move fast, we're forced to use speed which drains energy. Only then, we can use the sprint.

Why dont Crytek give the players the option to use sprint anytime by clicking the left stick once, and when they want to use speed, just click the stick twice.

or....you know...since the stick is anolog you automatically sprint when you push it all the way forward and walk by pushing it only half way

not sure why so many games overlook that....
