Wouldnt mind a sprint toggle/button in the meantime before we get horses and other means of travel. Or some kind of athletics skill to increase jump hang times and increased movement speed.
double-tap w will sprint, but it will cost you focus. there's also a sprint skill in light armor, and dash in air. the light armor innates will increase your base move speed and the effectiveness of the sprint light armor skill. also, if you have coconuts in the bank or from a stableboy, equipping them will move you at mounted speed.
