i think the Etoiles Mortants are a little like the sunset strikers. FT spec. but they are (bec. sec. attack) a little better than SS in that..
no shooting, but if you charge with SS -> no shooting.
=> i think you can bild a good force around it.
perhaps with 2 SSkimmer to soak up the damage and let them move close very early. the grunts stay back and shoot.
no experiance, normaly i play more a reactive style...
