So i've tested the list from the Clan Tactica I did last week. Mission was the Scouring and I was against Necrons with Tau allies. Started off pretty well but mistakes were made. I think it would have helped if we'd remember to roll for how much the objetives were worth when we got to them NOT half way through the game. Ended up with a 10 man tactical squad guarding a 1 pointer while 5 assault marines had to fend off a large unit of Necrons from a 3 pointer. That simple mistake could have been a game changer.
One thing I am going to do though is trade out the Master of the Forge for a Techmarine with Harness to save 15 points then downgrade the Plasma Cannon on the Dreadnought to Assault Cannon to give make him Venerable. Might be a bit more reliable then.
