Saw the codex today and made a list and whooped ass against Orks and space wolves.
A few notes
1) If you hated Nob bikerz then you'll really hate Paladin terminators, they are more durable, not as fast but short of having plasmas on everything and maxing on vindicators you are going to be steam rolled by this unit, period. I ran 8 with Draigo and they took 6 wounds all game. Give them the banner and counter attack from Draigo and they turn into gods. Did I mention they are scoring with Draigo and you can making them scouting aka outflanking?
2) Rad grenades, -1 toughness to the enemy when you charge or are charged, cheap as dirt and amazing upgrade for grandmasters, and brother captains
3) Mat the hack ward must have forgotton that Sniper means its base S3 against vehicles and that with turbo penetrator rounds is S3 + 4D6 and rending so D3 extra for each 6. Oh and you have inifinite rounds so you use hellfire to wound on 2+, I was capping space wolves like no tomorrow.
Basically this is what daemons were to fantasy, this breaks 40k wide open unless you tailor against it.
