Hi,
Thought I chime in with a few thoughts:
I personally think you've invested too many points in the DA & not enough in the Grotesquerie.
The problem I have with the NmD & WWP is that you will only get to use your FNP buff once you finally get the DA from reserves, which may not be untill turn 3/4. The 1st few turns without the DA buff, the enemies Alpha Strike would potentially be the most potent & you may find u wish the Grots. were already within the 12" bubble.
Only my opinion, but if u NmD you start on the table, to get most use from the buff. I will counter by saying I don't play @ 2000pts, so add salt......
Final & maybe most contraversial thought, your 3rd & 4th units of warriors are only there to get the Raiders right? If so, then drop the Warriors & you can instead get 3 x Lhameans with Lance Raiders instead. +1 Raider + 2 Lhamean - 10 Warriors = good trade
Since Ob. Sec. isn't an issue & nothing to say we can't bring 4 Courts lol
