I tend to disagree on the limited number of gals forcing me to use best all-rounder weapons - I think it creates a difficult choice, yes, but meaningful in that it makes me pick the weapons I need for the specific mission. For example, I tend to assault landed supply ships with only the eight gals I can fit on the Pachyderm, each with a well-defined niche roll. Up to four sniper/artillery weapons to clear the field, a melee scout or two for quickly silencing the baby nukers, and some heavier armor plus SMGs + shotguns for the boarding. I feel that rifles, one of my go-to all-rounder options for pogroms, have little place on that mission, especially when power armor may be in the mix.
I also don't think that having expendable gals means not bringing the awesome weapons - on the contrary, they can be the perfect testing bed for that new melee weapon or gun, and if they survive, they get put on the less expendable team due to stat gains. With a endless supply of swabbie uber-mutants, you have plenty of room for heroes toting the strangest and most effective weapons you can muster. In my view, with a smaller team you can't afford not bringing the big guns.
