In regards to wild weasels and pseudo-plasma, I think that AcTA: SF should simply ignore those rules, much as Federation Commander and Star Fleet Armada do. They're necessary in SFB for balance, but in AcTA I think they'd simply be a complication. (Not to mention ECM plasma, enveloping plasma torpedoes, plasma shotguns, sabot plasma, carronades, et cetera ad nauseam.)
