Played against a cadian Leman Russ army with a Baneblade variant last week (Two tank commanders, two enginseers, baneblade, 4-6 russ's...
I was toying with this as a fun concept the other day, but I eventually concluded that you really *need* some kind of assault screen, otherwise the tanks are going to be stuck in combat or falling back all game. Seems I was right.
For me, the biggest disappointment in the book is the Basilisk, which is just *not good* and the exact same cost as it was. Would have liked to see *either* a nice discount OR some kind of firepower boost. As it stands, it's just a sub-par lascannon squad for 50% more points.
The points increase on the plasma guns is making me rearrange my pure Scion/Assassins army. Basically had to drop two command squads to back fill the points for plasma just for my troops. Quite a bit of missing fire power there. However, with all the fancy orders, stratagems and what-nots I'll probably make out ok. Overall happy with it.
My intended list wasn't relying quite so heavily on plasma as that. Worked out that all I had to do was swap an Avenger Strike Fighter for an Executioner (which, given the new rules, has better damage output anyway).
I've been thinking a lot about Relics and Warlord Traits lately. There's a certain appeal to taking a Commander with Graf Toschenko's Plate, a power fist, and the Vostroyan Warlord trait and punching big dudes in the face with a stupidly cheap model. Of course, then you're also running your Warlord at the enemy, which is a good way to give them a point. Hmmmm...
