Add blast effect to the bombs and make the norden inacurrate when above their historical alt. Blast effects will allow players to get into formations and carpet bombs (cleaning ack in one or 2 passes or causing heavy damage to structures).
I really have to applaud Mizu and his other Japanese friends who in every occassion I see them in buffs, they fly them in formation. <S> guys!. The sad part is that they have to break formation to attack the field (one goes for ack, another goes for hangars, etc). Blast damage would allow these guys and any other buff-formations to make their runs in formation and CARPET bomb the base.
