Not really, In the current edition, the HBVG can stand on its own, although the synergy with the Master Engineer is well worth the points.
In the current edition, 30 is more or less a minimum for a parental regiment. You might consider using the Halberdiers as Detachment, increasing the Halberdiers and taking Swordsmen as Detachment(s). That would save you at least 30 points (or the CG) and even more if you decrease the size of the Detachments, points you could use for a musician for the DGKs, a BSB, or more items for your Captain.
Thanks for the replies!
The HBVG performed admirably in both games I had (read: lost) yesterday. One minor misfire, halving the shots on turn 2 in game 1, but other than that, pretty good thus far. I would like to include an engineer at a higher point level for the reliability, though.
I'm thinking you may be right on the Halberdiers. My swordsmen were essentially a squishy tarpit in both games. Not overly impressed with them, but using the swordies as a detachment might not be a bad idea for counter-charges and possible rank-denial.
Also, I just picked up 20 Crossbowmen, so they're probably going to find their way into the list.
As for Lores, Heavens was great in game 1, and I used Light in game 2 (against VCs). Turn one, Banished some Hex Wraiths.... from that point on I got a little too... obsessive... about taking out the terrorgeist. 3 Shems, 2 banishments... 2 wounds. My cannon had a "stick in the mud" misfire turn 1 and was dogged on turn 2 (dire wolves). My own damned fault for not paying close enough attention in deployment, otherwise his job would have been the Terrorgeist, and the Light Wiz could have used, what would essentially have been, 12D6 S4 hits on the rest of the army- which, truthfuly, Terrorgeist or not, would have probably won me the game had I not taken a personal, vengeance-based, interest in the damned Screaming Skeleton Bat thing...
