This is definitely a solid Butcher 1 list. Butcher 2 is.... weird. He wants a different army and he's hard to use in general. Generally speaking if you want a more in your face Butcher, I would go for Butcher 3. He seems to be the functional version of what they were trying to make with Butcher 2.
As for the list itself; Winter Guard are kind of all about the Rockets, particularly with Butcher 1 who makes them into double weaponmasters for a turn. It's not a bad list, particularly as a start without needing to buy anything extra, but overall I think the list really plays to Butcher 3's strengths over either of the other two.
Another thing to be aware of is that Berserkers and Marauders saw some changes in the last CID. Those changes aren't live yet, but likely will become final in June. Nothing that ruins your list, but Marauders are going up a point and berserkers down (and becoming MAT
6!). Gives you a couple points to work with.
Yeah, after I wrote this list I learned about the Armored Corps CID, I am tempted to swap the Marauder for another Berserker to fit in Journeyman Sorscha. Berserkers actually look pretty solid with their adjustments, ans Sorscha0 handing out Boundless Charge seems to be a great way to catapult a jack or the Butcher into melee. I know Butcher2 is kind of in a rough spot, but I think he just looks like tons of fun for casual games. Also tempted to drop the Infantry and Battle Mechaniks for another unit of Rifle Corps with 3 Rocketeers. The WG
Infantry seem really lackluster, even with their UA
, I feel the extra range will be more helpful along with 3 extra AOEs to dump into stealth models.
