So, I've gotten some feedback on my list from a few different websites and friends. While the reviews have been generally positive I'm not thrilled by them. I'm thinking about going an alternative route of having mounted squads in Chimeras working in support of the Russ. This is the list below. Please comment your thoughts.

Battle Plan- In early game, the Chimera basically hid behind the armor and work in support of it. Veterans disembark only to claim objectives (9/10th of time at least.) The Vendetta replaces the Quad as my anti-air. The Psykers make for cheap HQs that I don't need to buy a transport for.
A simpler list but every unit in it seems like it has more of a purpose. The other list seemed less focused. Plus, this list plays up the theme of armored advance a lot more. I can hear the creaking of treads now.
