Anyway, this is a surprisingly difficult stage that, in hindsight, seems blatantly designed for Impromptu and Guilt Delusion. The gimmick here is that the enemies transform the more they're hit, and when they're in full sized form, the enemies will counter immediately.
The actual solution here is to use Impromptu or Guilt Delusion, since Impromptu's rapid fire will not activate the enemy's counters. But cleverer players will know that you can use Alien T's Ult (which inflicts Silence and Disarm) to prevent the enemies from doing anything that's not an Ult (like their counter).
It felt quite nice to figure this out, though it really sucks that you're railroaded into the Impromptu powerup. Even with Alien T and Necrologist's Prayer, it's really hard to manage the enemy's Frenzy stacks
