|Fuck man, my Huskblade!|
IG is as strong as ever.. the Vendetta is just out of control. Not to mention Deathstrike just pours down S10 Large Blasts with not reduced damage, and the Hydras have Skystrike and don't allow Jink saves.
SW Frost Weapons are now only AP3, except for the Frost Axe which is basically a Power Axe. A few things changed so that Ragnar's Wolf Howl can only effect SW models, and Arjac has to issue and accept a challenge whenever possible.
BA loses the ability to Scout Smoke their Baals, most of their buffs like FNP and FC can only effect friendly BA models (no Allied bullshit), Red Thirst ICs can only join Death Company and a few weapon changes (like the Chaplains using Power Mauls).
DE definitely saw a nerf in Huskblades and Agonizers as they are now only AP3. Razorwing and Voidraven both lose Aerial Assault so the only one who has it is the Ravager. Allies cannot use the webway portal, and you definitely cannot assault when your units come out of them. On the bright side, you can now FF against Dangerous Terrain tests.
