Ok how about this setup for primaris death company?
1. 2 squads of 5 primaris death company each, equipped with heavy bolt pistol and chainsword, with one having a plasma pistol and thunder hammer.
2. 2 Impulsors
3. That leaves a slot in each repulser for a chaplain, and another primaris HQ or elite you want to go with them.
They rush to midfield, get out and fight as two squads in one blob with the chaplain and additional primaris character?
Pretty good?
Or should I just keep my idomitus assault intercessors as just that for now and paint my two impulsors red?
