Healing from MoK

[TheFishyOne]

Anyone know how much it heals a melee per swing? Is it affected by Double Attacking? The wiki is rather vague on all of this.

I sometimes have Melee asking me to cast MoK in places like Chardok Royals or Old Seb on mobs that don't have a DS, so I'm just trying to figure out if it's worth the mana/resists in cases where I am NOT removing a DS.

Thanks!
