My shock config that will get tested out real soon
Tantalus
3x scourge units with 4 blasters each (12 total)
Turn one, move+advance it 32" right onto primary targets doorstep (18"), melt their favorite toy. 12 blasters @ S8 -4 D3 and the 12 pulse shots at S8 -3 D2. It's going to hurt.
Now, I fully expect to be primaried in response - opening the door for the lultastic flocks of razorwings to move up and tarpit their shooters while the voidravens/razorwing jets tear the armor out of the secondary heavies. If the tantalus survives round one,we'll repeat the maneuver with the handy ability to fallback + shoot if needed.
I want to test it out as a Helion carrier -- load 15, do the same basic tactic above against infantry blob (15 splinter pods + tant weapons), then deploy the Hellions to go off and tie up units on the next turn. You can put them deep across the boar stupid fast like that...but not sure how well it will actually work
