So, the idea with this list is to not die
I am taking only infantry so enemy anti tank is less points efficient, added to that I am thinking of Stalwart and Warded as tactics so it's harder for high strength weaponry to wound and I get a save vs mortal wounds.

Tactics
The chapter master forms a fire base with the hellblasters and heavy intercessors, the rest form 2x assault groups, each with bladeguard, agressors and eradicators backing up the assault intercessors to head off and capture objectives with the characters split between the groups as appropriate to the mission/opponent
What do you think?
P.S. fluffwise I'm thinking Marines Errant - a chapter rebuilding after their gene stocks were raided would be mainly primaris, plus a mix of close assault units and gravis armour with no vehicles matches their fluff of boarding action specialists.
