I am guessing Patriarch Reginald Cross would be furious if anyone attempt to help him in this battle. I mean if Davia fired a white beam known to disturb expert pilots he would probably attack her. Same goes for the Battle Criers unit who also wield the Crystal Rifle. Lucky for Reginald, I doubt any of the Experts are availible to help with 14 more opponents to fight. Also the regular mechs pilots are in a thought fight with slightly more dwarves mechs pilots overall.
