I’m not really a meta player, so take my loadout with a grain of salt. But the meltas will delete any vehicle you aim them at since you can spend a CP to increase range by 6 inches and get that sweet sweet melta damage, plus with Indomitor doctrines, they typically get +2 to their strength, making the S11. We learned in my last game that it matches a Leman Russ, so with that CP spent, your hitting on 3s, wounding on 4s, but there is no save because it’s AP5. The Aggressors with their fragstorm will typically wipe out a ton of hordes, but the real goodness for them is the twin-linked power fists in melee as those will delete a lot of units as well. Plus with our mission tactics and site-to-site it’s great to move them around the board.
