So here's what I came up with for my Daemons/Traitor Guard list, which I submitted by September 1st, so now I can't change it. Kinda dum policy they have making us finalize the lists a month in advance but oh well, here goes:
HQ: Bloodthirster/Might/Blessing
HQ: Herald of Tzeentch/Chariot/Icon/Bolt/Master
T1: Horrors x 9/Bolt/Icon
T2: Horrors x 8/Bolt/Changeling
T3: Plaguers x 5
Elites 1: Flamers x 4/Pyrocaster
Elites 2: Flamers x 4/Pyrocaster
Aegis Line/Quad Gun
HQ: Company Command/Camo/Regimental Standard/Astropath/Master of the Fleet
T1: Platoon Command/Bolt Pistol/4 x Grenade Launchers
Infantry Squad/Bolt Pistol
Infantry Squad/Bolt Pistol/Melta Gun
Heavy Weapon Team/3x Lascannons
Heavy Weapon Team/3 x Missile Launchers
Elites: Marbo
Fast Attack: Vendetta
Heavy: Manticore/Camo
I've had good luck until I faced a drop pod army, which melta gunned my Manticore (the dude landed inside the walls to avoid my cover save), and flamered my entire Company Command Squad (no cover from flames!). So since I can't change my list I will have to be careful about exposure to such events again, but does anyone take Carapace armor for their Imperial Guard? Of course not every army has Deepstriking stuff.
I was going to keep an Infantry Squad in the Vendetta for dropping in somewhere depending on the mission. Any other thoughts for future improvements? I want to try out the Medusa Siege Gun too with covered cockpit and camo also (with Bastion Breacher shells of course).
