I'm a bit constrained by my current models as all I have left are warriors, wyches, haem, sucubus, 1 more venom, and the gangs box set. Looking for general list suggestions and answers to some specific questions:
1. Should I bring a few splinter cannons over blasters to deal with horde lists?
2. Considering dropping archon and to open up points to replace blasters with DL's. Should be able to bring a full unit of DL scourge, but I liked using the archon 2+ to soak overwatch since the raider seems to get blown up before the incubi can charge.

Went 1-2. Probably would have gone 2-1 if I knew the rules a bit better. List that gave me trouble was a harley ynarri list.

Incubi did basically nothing, drazhar did less, archon had a bit of an impact absorbing no wounds until his save failed. They lost to two troupes in the one game where they might have been really useful. Went up against a list with 8 librarians, they managed to kill 3 of them in 2 turns. Other than that the list worked as well as could be expected. I think it'd be competitive if I find something better for those points.
