Correct. But can’t use BrS in a ST situation if you don’t play BrS is what I’m saying 
I was able to log in and dink around a bit and this is absolutely true. From the way I had read it, I thought we’d only get 1 stack of BT that could stack up 2, meaning we’d need a third cp builder every round. But we get 2 stacks and as you mentioned, with how things fall/line up, we get to go into that second BT charge strictly Shreds into Bite which is nice.
And a little energy pooling is needed, but not horrible to account for once burning through 2 charges of BT. And Rake falls in like just about perfectly for being refreshed.
