It always did that. The Violent was just a byproduct or Race : Draksar. Which never made sense but was a nice bonus. Guess they finally caught on
In case someone missed me posting this in the general discussion forum: Violent hasn't been removed from taint. Like, jib said it was a by product of gaining race: draksar. If you cast it on a unit that isn't a draksar it gains race draksar, regen 3, draconic force, and violent. Violent was never in the spell description it was just for a while almost all draks had violent because it was the drak racial. Gaining race drak gained you there racial. Casting taint on a drak champ gives you regen 3 and drak force but it will not add violent to a drak that doesn't already have it. It was like this pre revamp too. I tried casting taint on Drak Morph, because she was one of the few drak at the time without violent, and she didn't gain it. If you want 9 range drak archers with fury you're going to have to settle for rage band and not taint. Sry.
