I like your dual
SS + 3 @i weapons for the Wulfen
I like your use of Wolf Claws on the
TWC
I like your use of the Dreadnought in Pod. personally, i'd go with Lucius pattern pod to keep him alive.
Herald is expensive...
imo go
WGBL + Claw or the ap2 Relic, or try for Champs of Fenris to get 'Krakenbone Sword' for @i5 AP2.
having
SS on -every-
TWC might be a bit much, but that just depends on who you play against.
Me:
I'm one for variety.
Having dual Wulfen, not -bad- but podding in one into cover then creating a zone between them and the podded Dread is rawesome.
I'd razorback or pod in the troops,
imo. I've had a lot of fun with a Stormwolf w/ Iron Priest and 5 Servitors + runepriest, and whatever else to throw in that batch of stirfry. Super Cheap, and way mean. Servitors with servorarms strike w/ 2 attacks and S6 AP1, 2+ wounding and 4+ glancing. OUCH for just 10pts a pop.
I've been working -hard- on a list of pretty much
CC w/ shooty Space Wolves, trying time and again from many different formations accross the
40k 'verse, and this is my current rendition - if it strikes your fancy to see another in pursuit of this Space Wolf
CC army:
