90cm-0cm is ultimately much better for the NC than 150cm-30cm, dunno why any of the pro power-NC would mind it.
I've had bit of a reversal in my NC feelings. Due to their rare nature, theres no problem in somehow limiting the NC, and gives Admech more personality.
At the same time, in that case, I believe the NC should be more powerful in that case, so it would function better in singles.
Say take current NC rules, except 2d6 scatter always, and D3 damage from template, rather than 1.
