Stealth is the first, AOE, much more AOE

And charging forgeguard unit.

for example:
Captain Bartolo Montador (*5pts)
* Vanguard (5pts)
Arcane Tempest Gun Mages (Leader and 5 Grunts) (6pts)
* Arcane Tempest Gun Mage Officer (2pts)
* * Mule (8pts)
Lady Aiyana & Master Holt (4pts)
Eiryss, Mage Hunter of Ios (3pts)
Master Gunner Dougal MacNaile (2pts)
Okay, there is no Foreguard, but there is Dougal and a full ATGM + ua w mule for AOE, Eiryss and A&H in stealth, to hunt them down
And the ATGM doesnt die more quickly than the MSHF...ATGM get 15DEF, back in a linear obstrucle, they've got DEF19

Dont run forward, wait and shoot
