I've cleared the first extreme and peeked into the second, my general findings of the DRK changes is the job is actually harder now, which I feel is unintentional.
That 1200 mp per minute we lost is actually really important, as with only 3 mp spenders between burst windows, it indirectly makes Darkside Management a real thing, which inturn means TBN is even more punishing if it doesn't break.

And whats worse is post Burst window, I'm finding it takes significantly longer to return to 3k MP for TBN usage. This bit feels unintentional.
