Sounds good to me
That is honestly a really stupid statement. That's like saying you are attached to a particular bottle cap color on a favorite beverage. Sure, maybe you "like" it but it ultimately doesn't matter and if you complain about it being changed for no other reason then "this attack is a weak DOT only used for OP" then thats simply silly.
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).
Love rend, shame to see it go the way of the Dodo
