That’s not it at all.
There’s a difference between not having amazing AoE, and what we can see with BM currently. Especially since the only reason BM is where it is, and not even worse, is because of Wild Spirits. Again, reliance on borrowed powers for something that should already have a solid base, where borrowed powers should only slightly enhance what is already there.
Agreed, I never said that I expect them to make these changes for 9.2.5(as an example).
