I don't like that air stance is being changed to only become useful for TWF.
It really is going to hurt staff using acrobat monks.
The problem is since it grants the increased dex.. its necessary for max AC and they synergy with the new Acrobat I changes to how its applied to S/A Damage, not to mention the loss of alacrity.
Not to mention that you will be negating a 13/6/1 rogue/monk/fighter as a viable build since the additional monk levels will do absolutely nothing worthwhile.
Eladrin I don't suppose you would consider this as a proposed solution.
Currently -
Monk Air stances now grant a +5%/+10%/+15%/+20% insight bonus to the chance to proc off-hand attacks instead of an insight bonus to attack speed. (Enhancement bonus to attack speed remains.)
Change to -
Monk Air stances now grant a +5%/+10%/+15%/+20% insight bonus to the chance to proc off-hand attacks instead of an insight bonus to attack speed. (Enhancement bonus to attack speed remains.) AND Monk Air stances now grant a +5%/+10%/+15%/+20% insight bonus to the chance to proc a double strike when using a two handed weapon.
Or something along that flavor. That way air stance is viable to all fighting styles.
Will look for a response.
