Here are the changes that I have at the moment. I would love some feedback before I lock them in to 2.1.
Unit changes:Venerable Dreadnought - RA4+, CC3+ +75points?
Wolf Guard pack- CC2+, FF4+? added the omitted
may use drop pods ability in the notes. Used the proposed stats as some felt they were a bit blah.
Swiftclaw attack bikes - added multi melta 5+MW, 5+ MWFF. I know two other chapters use this AB pattern but the codex mentions SWs doctrine for their bike/attack bikes is one of thrust attacks that do maximum damage possible as quickly as possible rather than long range recon.
Long Fangs - added the omitted transports. have gone with the 2x twin ML option. I would like to keep the stand alone formation for now.
Wolf Scouts - replaced the plasma guns and sniper rifles with a heavy Bolter. 2 units may add the sniper ability +25 points each
Fenrisian wolves - embedded the new thunderwolf character (includes thunderwolf stat in one unit) as proposed.
Army list changes:Heroes may add only 1 fenris wolf unit to their formation. I figured one unit extra per hero won't make a massive formation and it adds to the cost. For modelling purposes it will be fun and look fluffy (excuse the pun

)on the table. Wolf unit will gain ATSKNF - It's under the hero's leadership and is essentially part of a "family group". Only thing i think needing testing is the cost. +20 points?
After Neal Hunt's point about confusion, I removed the embedded Heroes from the Grey Hunters and various Bloodclaws packs. It's not exactly what I wanted but it
is clearer.
Venerable Dread - 0-1 or "add up to 2 to the formation?"
Heroes - Removed Fenrisian Wolves and added the omitted bloodclaw type to the "may only take one hero" rule
Added the sniper ability upgrade for the wolf scouts
Adjusted the cost of Grey hunters and Bloodclaw packs after removing embedded heroes
