Welcome back!
As you can see you are really not alone coming back after many years of abscense, there's more of us!
Really good reports and it helps a lot with the thoughts for us to develop.
I would strongly recommend you to play with the warlocks though...they are insane.
Their 4++ means they win the chaff war with ease, combined with 2S4 poison ASF attacks they rip anything apart.
(The cost of 5 is 125 which is a good price for a chaff unit).
Combine that with the fact that they can 6-dice soulblight every single turn without risking a dimensional cascade is devestating!
(Sure they'll slowly die but I ususally only loose one)
The enemy army will be down 1S and 1T which can be used against an enemy unit to stop him from wanting to charge you.
