pDenny wasn't Apotheosis, she was prime.
Scything touch is damage, carnage is hit.
Kromac is pow 14, his only upside in melee is a) 14 fury and b) he can actually get to the enemy caster. Butcher is better in melee, but butcher is better than everyone in melee. One demo corp is going to need an awful lot of 6s to one shot terminus, and can't do it at all if Darragh is doing his thing or Terminus got any souls.
If the enemy shoots Terminus with an unboostable pow 10, he can just take it. Armies tend to not have all that many high pow boostable shots.
