That sounds very reasonable to basically give a class Feint with no CD and longer duration. Definately wouldn’t be broken.
They have their advantages and disadvantages… they’re good at avoiding damage and at dealing low constant damage, thus good in dampening. That’s why we see only Frost Mages tho. And they don’t bother sheeping rn.
It might be broken, but Poly duration will be also reduced, it will still remove dots and it will still break on damage, meaning Frost Mage might not even opt for it.
Fire and Arcane probably will tho.
