1 organ gun currently cost 120pts, gyrocopter cost 80pts. So for 380 you can take 2 organ guns and 1 copter, organ guns hit on 2s(if copter is near target otherwise 3s), wound on 3s, rend 1, dmg 1.
Have both organ guns load 3 barrels(can do 1-4, but I think 3 is reliable and deadly) so each rolls a d6, on a 3+ they get 3d6 shots but if they fail that roll they jam.
Plus the copters guns, could take the brimestones for extra poke from a safe range, or go all in and take steam for maximum hurt.
All in all that's a lot of stunty firepower, might add this to both my Seraphon and deepkin army xD.
I think we might see point and even some rule adjustments for all the mercenary units. Lots of the models almost never see table these days.
Edit: Also they've shown all of them 8 in that post plus the 2 from forbidden powers is 10 mercs.
