Sounds good to me
Honestly it is going to have the combined power of the old deep wounds and rend. The only real noticeable difference will be that you wont have to apply it at the start of a fight.
Happy about this. Never was a fan of the whole "apply something relativly weak and waste time re-doing that on every new target just to get access to this stronger, shinier, ability" design choice they took with Rend. Real pain in the arse, and a rather significant DPS loss, on anything with many new targets such as Gunship 2.0 (Warmaster).
Live in fear, for the bullsquirrel is near.
The entire internet needs to be aware of this
