Had a game against Orks last night. Ended in a 6-7 defeat but what a game it was. Still need to tweak my 1500 list as im 60pts under right now (I gave my libby armour indomitus to make up the points). Centurions did as well as could be expected they did have a good target with the meganobs he was running but they had 5+inv and FNP thanks to Mad Dok Grotsnik which kept them alive long enough to get into combat. Sternguard got me first blood on the meganobs battlewagon and almost took out a whole squad of boys thanks to heavy flamers/flamers with the re roll. Still need to play about with them and get the best out of them. Think im possibly being too aggressive with them. Ironclad had the best performance from him yet he heavy flamerd some of the big gunz and then he climbed up the skyshield flamed all the lootas there than next turn jumped down rolled a 12 for his charge which he needed and made into combat with the meganobs where they took off his last hullpoint and killed him. Still an epic charge though. Had it not been for Grotsnik I think I would have taken the game as I would probably have taken out the meganobs+his warboss giving me the extra KP I would have needed.
I'm running
Lvl 2 Librarian
10 Sternguard, 3 Combi Melta, Combi Flamer, 2 Heavy Flamer (combat squadded), Drop Pod
Ironclad, 2 Heavy Flamers, Drop Pod
10 Tactical Marines, Combi Flamer, Flamer, Multi Melta, Pod
10 Tactical Marines, Flamer, Multi Melta
3 Centurions , Missiles and Grav Cannons, Land Raider
which leaves me about 60points to play with. Possibly a speeder? Not sure 1 Speeder is worth it but im not sure how else to spend the remaining points
All in all though the switch in playstyle from my Chaos is giving me a lot more fun with my lists. It took a while to switch from a more gunline approach to drop pods in the face but all my games have been a lot better and the losses have been a lot closer (apart from my game with the 2 wraithknights and wraith guard with death flamers)
