Here's a fun list idea I had for the people who really don't want to run a Primaris army*. If 6 Raven Guard Assault Centurions are good, then surely an army full of Centurions is even better?!

1 unit of Cents can be Ambushed up, the 2nd Infiltrate forwards, the smaller 3rd unit can SftS to come in turn 2. That still leaves maybe 6cp for midgame use. Meanwhile all the supporting chars can run up to stay in buff range, give advance and charge boosts, turn off overwatches, and heal back up. I was sorely tempted to make all those guys Stealthy too, but decided on Long Range Marksmen and hoping for some midfield cover they can hide behind.
*yes I used 2 Primaris, but they could be downgraded to normals.
Edit: changed
dev Hbs to grav. Had forgotten they were same cost now.
