So anons,
I'm building a list with some Primaris as I think its probably more effective then the stuff I've been running.
Idea is basically Intercessor spam and moving up the board to just rely on volume of shots, rerolls, and extra wounds to be dangerous while the banners let me get some extra wounds in with the dying marines.
List is as follows:
Battalion:
HQ:
Primaris Lieutenant w/ MC Autobolt rifle
Primaris Lieutenant w/ MC autobolt rifle
Troops:
10 Intercessors with Bolt Rifles, Grenade Launcher on Sarge
10 Intercessors with Bolt Rifles, Grenade Launcher on Sarge
10 Intercessors with Bolt Rifles, Grenade Launcher on Sarge
10 Intercessors with Bolt Rifles, Grenade Launcher on Sarge
Elites:
Primaris Ancient with Bolt Rifle and Pistol
Primaris Ancient with Bolt Rifle and Pistol
Spearhead Detachment:
Primaris Librarian
Primaris Captain w/ Stalker Bolt Rifle and Bolt Pistol
Heavy Support:
Hellblaster Squad: 7x Hellblasters
Hellblaster Squad 7x Hellblasters
Hellblaster Squad 10x Hellblasters
Hellblasters are pretty much the AT and Hard hitting hammer while everything else either is there to eat charges, hold objectives, and whittle other things down.
Chapter-wise, I'm Torn.
Dark Angels give me a good Plasma tactic and better Morale defense, along with rerolls of 1 when I stand still, along with a few debuffing powers on the Libby.
Vanilla Marines give me the Banner of the Emperor ascendant for slightly more reliable death shots on around one half/quarter of the formation while the Raven Guard chapter tactic gives me some better defense by being harder to hit outside 12".
I know that melee ability is very low on the list considering that I've no power weapons but I've pretty much figured that Melee is a lost cause for Primaris Marines.
