1) Which fleet list do I go after? The Ork Armageddon Rules, that are bundled with the D/panzee or the Clan Rules? The Clan rules seem more fun, but also infinity more convoluted. For simplicity the Armageddon Rules have been recommended over the Clan Rules.
2) What models would be good to help me understand both the game itself and Orks for 750? The end goal is 2000 points, but I'm not sure where to start. The following has been recommended to me.
Warboss w/ Extra Powerfields
Karrier Terror Ship w/ boarding torpedoes
Kroozer w/ heavy gunz (so you can see what Savages are like without buying them)
2 squads of 2 brutes- quick, maneuverable, and not worth shooting at.
one squad of a Ravager and 2 Onslaughts.
one squad of 2 Ravagers and an Onslaught.
3) What are some general Ork tactics for playing the army?
4) What are some army specific tactics (tactics specifically against other armies, not to be confused with list tailoring)?
