I'm also a returning player doing 3rd co.Primaris. I haven't gamed since 5th, but still collected my plastic crack. There are two LGS and a GW within a reasonable distance. Now that I have the time to play again Ive decided to assemble and paint two different forces of Dark Angels to play against each other. I want to learn the game. Playing Green vs Bone will teach me the game and how the two function. Hopefully.
First is 3rd co with 10th and Bladeguard from the first. I want to paint new models and make friends so this is what Id like to run. Leading it is my own 3rd Co Lazarus. Same guy, converted model. Then it's all Primaris with a Chaplain, Ancient and Librarian. Squad of Hvy Intercessors and 5 Hellbaster Heavy Plasma Incinerators guard the DZ and home objective. Infiltrator and Incursor squads take the corner points of the midfield. They hold for one turn while Bladeguard, CC characters reinforce one point and Assault Hellbasters reinforce the other and push forward. Plasma Inceptors launch a feint/false attack in the enemy deployment zone. It's basically just trying to hold onto objectives and make my opponent either reactive or stuck fighting me over an objective we both contend.
Second list is a Deathwing Vanguard detachment. It's lead by an Interrogator Chaplain in Terminator armour and Belial. I need to pick up a librarian in TA, but the Phobos dude is cool and still has the Deathwing keyword. I have enough to run 2x5 DWK, 2x5 DWCC w/TH/SS, an apothecary, ancient and champion in TA. Contemptor, Redemptor and Crusader or Redeemer for the big toys.
Please do post up your progress, be it finished models, custom lore about your 3rd company or your w/l tally I'd be beside interested. I'm prepping my Phobos and 3rd Co units now. I'll keep a log if people seem interested. Good luck! Hope to see some of your work soon.
