So when monks get stuck at range for whatever reason, they can do basically nothing. A basic spamable ranged attack would be easy enough to implement, and they could even just give it the old One-Ilm Punch animation for launching the attack. As a flavor for it, it could also have a minor secondary effect based on the form they are currently in when they use it, like a minor amount of aoe or a really short heavy. Or even just be a guaranteed crit when used after Thunderclap.
