Hey guys,
So I'm finally taking the plunge into the heresy and after much thought and badgering I've picked mortarion's boys as the legion for me. Consequently this is the first list I've written for the Age of Darkness and I need some feedback from wiser heads.

Praetor in Tartaros armour with Power Scythe and combi bolter (Rite of War -"The Reaping")
-Deathshroud squad (4)
-Land raider Phobos

TROOPS:
Legion Tactical squad (20) Vexilia

Legion Breacher squad (10) Vexilia, power scythe
Legion Heavy Support squad (10) Heavy Flamer (chem munitions) Rhino
Legion Heavy Support squad (5) Plasma Cannon
Legion Heavy Support squad (5) Volkite Culverin

ELITES:
Contemptor 2xCCW with Heavy Flamers (chem munitions)
Contemptor CCW with Heavy Flamer (chem munitions) Kheres Assault Cannon

HEAVY:

Grave Warden squad (5) Heavy Flamer (chem munitions)

Thought I'd play up the whole chem munitions and harde of foot sluggers side of the Death Guard and would really appreciate what you guys think.

It's an intersting list albeit not the most mobile.

I feel that your LR Phobos will be blasted and you will be foot slogging across the battlefield that being said you could use the couple of mobile units to reinforce weak/exposed areas.

I think you make up for the lack of AP weapons with the number of flamer templates and making your opponant roll high amounts of dice, the best way to kill termies :)
