Here is what I got from the vague respose. Only 2 (Quote: "A couple") of lashes per offbalance, but apparently removing the 5s ICD whip cooldown for applying offbalance.
Good fix to the perma spammable powerlash for PvP by not adding some massive cooldown, instead taking the more logical, stun consume, and if no stun, give one extra lash. Also indeed a fair buff vs multiple targets if the 5s ICD is removed.
I have some real concerns about this though, since it can apply offbalance so easily, have a free cost/extra dmg/stun proc so easily. Happy due to the state of MDK in OW, especially solo, but concerned at balance issues in how OP this could be, especially in duels.
