White Scars seems to be the "net list". Highly mobile and can max out grav weapon shots while moving. Ally with SW and the grav weapon+JWW combo will erase almost all MC from the table since they have to test on Init 1.
Not to take anything away from White Scars, they do seem very good, but I'd like to try something different, as tempting WS are.
what he said, you can scout and move 6 and flame but thats it.
if you really want to do an in your face flamer list try drop pods
i like the UM chapter tactics for drop pod lists, sure they're one use but the rerolls for melta guns right out of the drop pod is nice when you really need that vehicle gone
i want to try out a kantor list which means i have to use fist chapter tactics, they look ok but need to have dev squads to get the most out of it
UM also look good, it's a little of something for everything whenever you decide you want it and Telion is tempting. I'd love to be able to shoot out whatever model I want in a squad without having to rely on rolling 6s to hit.
and as much as I like drop pods, you only get half on turn 1 which I want for dreadnoughts with sternguard in reserve while the rest of my raven guard units move up quickly to support the dreads that just dropped. I think most people look at RG tactics and see better options but I'd like to be able to make it work.
Also I've been looking at honor guard and they look like the best unit in the game. For 25 points you get a marine with 2 attacks, wears artificer armor and comes with a power weapon. In comparison, a veteran sergeant in a tac squad costs 24 points (14 for the marine and 10 for the upgrade) and only gets a second attack. Honor guard get very little options but besides not having an invuln, they need nothing.
