Another comment on the shotgun discussion which is similar to this comment.
Edit: Many shotguns are not very good because armored targets resist them easily and in the situations were they would help, a machine gun or a rifle will work equally well without its drawbacks. It shows in Meridian's LP and myself I only favor the blunderbuss.
Shotgun stats look good on paper. So I tried them out a bit initially, but found they are not so good for the following reasons:
1. The long range gals get heavy weapons, sniper rifle or similar. Much better accuracy on long range than any shotgun.
2. The short range gals for storming ufos or buildings get usually a strong melee weapon, which deals much more damage than any shotgun.
3. For the rare cases where you would need a medium range weapon like shotgun there are plenty of good alternatives like ninja stars, fuso knives, heavy pistols, powder bomb .... Those alternatives are light and fit easily into the quickdraw slot of every gal, which does a shotgun not.
So in the end, there is not much need for a large dedicated medium range weapon, even if the stats were a little bit improved.
Of course everybody has his own playstyle, but with the current balancing I see no reason to equip a shotgun on any gal (which is no problem, because there are dozens of other cool weapons). Maybe if the shotguns had a special ability like discussed above: TU, stamina, lots of stun, or morale damage would be an interesting selling point.
