Also, does Gunslinger/Commando affect normal weapon sway/spread?

I've haven't seen anything specifically addressing whether they do or not.

Thanks.

Trigger Disp/Fast Shot both impact VATS. Check the Wiki on it. Some people have reported a big impact in VATS. Personally, I do not like either trait.

Commando/Gun Slinger/Sniper are only good in VATS.

and this is why they fail, Sniper is particularly useless, as most snipers are too far away to use VATS satisfactorilly.

I disagree. It is worthless for long range, but it rocks mid-close range. Espeically with a high spread weapon like a shotgun or SMG. Love head shot shotgun blasts!

I guess the problem is calling it "Sniper" when it's intended for relatively close range (much less use a shotgun!) I think I would rename the perk to "Get Ahead" or maybe "Heady--That's Headly--Lamar"
