I'll be honest and say that I'm eyeing a lot of Path of War from the perspective of a melee build (weapon and/or unarmed) as opposed to ranged. In that light, indeed a lot of the maneuvers are useable at range, like an arcane archer on steroids.
To return to my Flux comments; Is there some design goal/principle preventing you from allowing long ranges or wide areas? If not, perhaps Lance of Power could allow animus to upgrade range in addition to damage (for example use 1 animus to increase to range X, then an extra 2 animus for +4d6 damage). This way you don't need a lot of different versions of the same power as each power is highly customisable (uniquely to the mystic). Similar things could be done to other maneuvers.
For Master of the Elements, since duplicate stances are a no go, would it be possible to move the stance to a lower level with a decreased effect (Elemental Body I) then allow it to gradually scale (perhaps even to Elemental Body IV at Initiator Level 17)
I'll try to make an account on GitP and join the discussion there.
