The title say it all, really.
Allow players to press their “dodge” key while falling, causing the character to roll. If the character is rolling when it hits the ground, reduce falling damage by a percentage (ex., 25, 33 or 50%), stacking with fall-related traits. Should also work when sliding down hillsides (which GW2 sometimes interprets as a sequence of falls, even though the hill follows a smooth curve).
Naturally, this would consume energy, same as a normal roll.
If the player times the dodge incorrectly (i.e., character has already finished rolling when it hits the ground), then it should take the full damage.
I believe the animation for this is already in the game (one of the “diving goggles” skills).
Not only would this feel “natural” (after all, that’s how skydivers, etc., are taught to land), but it would reward players for an action in a situation where they currently can’t do anything (if you fall, your fate is kind of sealed; all you can do is wait to see if your survive or not).
