I just finshed my first army (2000 pt. Necrons) and now I'm making the army I've had in my head for quite a while: Nurgle 'Nids. A splinter fleet accidentaly ate nurgle world and got infected. They play just like regular 'nids but have biomorphs to suggest their infestation i.e. spore cysts, toxic miasma, symbiote rippers (nuglings), implant attacks. They dont actually HAVE to have any of those, but they feel like they belong in the army.
My problem is that I have no clue where to start. The 'nid codex is chock full of stuff that only serves to boggle me. I want a "gaunt hammer" kind of deal with tons o' crapgaunts that tie up enemies while my raveners, suped up warriors, stealers etc. get into the fight, but I dont know how to work in anti-armor and other units that balance a list. I'm shooting for 2000 points in the end. So all you magnificent norn queens/ Hive Tyrants out there... help?
Thanks,
-Eli
