Yeah, I'm thinking Meph too. I'll give it an update tonight and post it. I've been playing both Libbies and Mephiston in my lists, and the biggest disadvantage so far has been Mephistons inability to deep strike.
On the other hand, Blood Lance is insane for deepstriking and taking shots at a line of vehicles and the shield does wonders since everyone builds against marines.
Anyway, looking the list over, will post later.
Automatically Appended Next Post: Alright I made two lists. One that swaps out a lot of the expensive vanguard vets for some land speeders and one that cuts the vets out in favor of some special characters while still trying to keep the lance/shield combo.
List 1 edited (2485 points):
Keeps a single vet squad in there to snipe infantry, 2 honor guard squads to snipe vehicles and then 4 assault squads with priests/libbies attached for the dirty work. The left over points are spent on land speeders with multi meltas.

Alright so this list is a little funky. It retains two librarians for shield/lance, while adding expensive HQs. It has about 10 less bodies on the table, but should be fun to play. Still has points over so that the libbies can come in with pods, but the idea would be to start them on the table. Might be short on bodies.

Anyway, feedback appreciated. The only thing I'm not really worried about with these lists is vehicles. There is enough meltas in there to do some pretty serious damage.
