I just played a game where I had 3 enemy rows of biting frost, then I played 2 wild hunt riders in the melee row to increase the damage twice, but what happened was it removed the previous damage and reverted the frost damage back to 2, is this working as intended? Seems increasing a row's biting frost damage 2 times would make it go from 2 -> 4, not 2, to 3, back to 2.
