Well... I completely bashed the crap out of Matt's models at first (though mainly cause we allowed him to barge through walls, making the buildings collapse on top of him... - he insisted... the anxious little bloke...)
But then in Bremen, he took the lead almost directly from the start.. and was real hard to bring down... So I say it's a varied enough band to give it a shot... though brutal to face in close combat.. they are few, and if you manage to take down the right models, you can stall their advance/growth... if you allow them to grow... they become a real pain...
