Game Mechanics Airborne Twain's Arc Major ID/Tree Node

My suggestion is as follows: A major ID or ability tree node that allows you to cast Twain's Arc midair, at a slight detriment to damage. Currently, shifting - which is required to charge Twain's Arc - triggers escape's stomp and as such makes it impossible to get the skill to fire before hitting the ground. The mID or node would replace the stomp following a shift with a slow-falling effect, allowing the player to stay above the floor as Twain's Arc loads up. Escape could now be used as a genuine evasive maneuver to avoid swarming enemies on the floor while trying to land a slow damaging skill.

Why I think would be neat:
1) I believe it would help with melee Sharpshooter's AoE problems, as shooting over hordes of small enemies to focus one big target would be much more viable. Getting swarmed would be much less of a problem if you're still trying to attack.
2) Escape would become offensively useful beyond just the slight damage offered by Escape Artist
3) I think it'd be cool to be able to snipe things midair.
4) There are basically no major IDs that interact with melee archer yet.

Potential issues I see:
-Dev time. Unfortunate as it is, CT are busy.
-Unforseen or problematic interactions with other archetypes and spell builds (The effect might have to cancel sooner if Twain's arc isn't started).
-Purely melee focused bosses being cheeseable (to be fair, the same goes for Acrobat)

Feedback on the idea/pointing out flaws I might have missed in the comments is appreciated.
Thanks.

 

Agreed! Maybe to solve the AoE issue, Twain's Arc could do a little AoE explosion on the first enemy it hits that also deals damage to enemies around it.
