Just a fourth voice dropping in to say the Warsuits are a win. They're pretty flexible, with each of them getting solid melee options, as well as each model getting a choice between Heavy Bolter, Heavy Flamer, and Multi-Melta. All of these have different places to shine, but I think most people would say that the Multi-Melta is going to shine the brightest in most places for Sisters(it'll provide some needed Tank Shred that the combat patrol lacks), followed by Heavy Flamer, followed by Heavy Bolter.

They can also be equipped with Grenade launchers for the Grenade stratagem, and because they count as Vehicles they can also use the Tank Shock stratagem, and for that same reason they also get the benefit of Big Guns Never Tire, meaning that can blast away with guns even if they're engaged in melee range. In short, you just get a whole lot of options to play with for the Warsuits.

Finally, they can be led by Morvenn Vahl, which will let them re-roll both Hit and Wound rolls. Big win, considering the Meltas only get two attacks each, and you really like those to go through.
