Ogrun Assault Corps

I bought the OAC (Ogrun Assault Corps) a long, long time ago. And I haven't really played with them in any list so far. I've never had a reason to include them, since there's always something "better" to add in Cygnars huge list of mercenaries. But I stumbled upon a thread were they where discussed as a solid choice against Legion, a faction I've always had trouble with.
But what do they really offer that, say, Boomhowlers doesn't? They have 1 less SPD and ARM, the 1 extra point of STR doesn't really matter since both units are P+S 12 in melee. They have more wounds, but lack super-tough. Well, I guess the only thing that they add are a powerful Battlecannon with 12" range, POW 12 and a 3" AoE. Combine that with Jonas Murdoch to give the unit Assault and a Warcaster with Snipe and we got something going.

Another thing to add is the "new" ruling about ranking officers, which means if you include Murdoch they can get the benefit of being trenchers for the purpose of Maxwell Finns Desperate Pace. Now we suddenly have a unit that have a 26" threat range (5 spd, +2 desperate pace, +3 charge, 12" range on battlecannons, +4" Snipe). My guess is most players won't see that coming. They still need to hit with stuff with their cannons, but that's why we play Cygnar. Rangers and Deadeye for the win.

Now, you still want them to survive in case they overextend. Arcane Shield will put them at ARM 18, and with pStrykers feat we're looking at Ogruns with impressive ARM 23 and 8 boxes a piece. That should hopefully protect your second wave of Stormknights to enter the fray unharmed. Well, that's the theory at least. I still haven't given them a try yet, but I will.

The list I'm gonna start with is of course pStryker since he has quite a few tools to help OAC with.

50/50
Commander Coleman Stryker (*6pts)
* Lancer (6pts)
* Ol' Rowdy (9pts)
* Sylys Wyshnalyrr, the Seeker (2pts)
Ogrun Assault Corps (Leader and 4 Grunts) (9pts)
* Captain Jonas Murdoch (2pts)
Rangers (5pts)
Stormblade Infantry (Leader and 5 Grunts) (5pts)
* Stormblade Infantry Officer & Standard (3pts)
* * Stormclad (10pts)
* 3 Stormblade Infantry Storm Gunner (3pts)
Professor Victor Pendrake (2pts)

Against Legion this should be a solid list. The plan is quite simple. Start off with casting Snipe on the OAC and give the Lancer a focus to run. Pendrake uses Beast Lore on the OAC. OAC uses assault on a suitable target (if there is one). The rest of the army follow up behind the Ogruns. Second turn you give Arcane Shield to the OAC and assault a second time. The Lancer might have found a target to Earthquake or you simply use Beast Lore again. Pop the feat with Stryker and hopefully you opponent now has to deal with 5 models with ARM 23 and 8 boxes each before the rest of your army is in melee. Sounds easy enough.

I might want to skip the Rangers and add the Black 13th to remove some support units. Perhaps I could even drop a Storm Gunner and get another solo in the list, like Gorman, Lanyssa or Rhupert for pathfinder if I find it necessary.
