Sneaking is kind of oddball since in some situations whole party must go through
I agree on it being oddball, but not really for this: I think there's only one place like that and it's trivial even with everyone at stealth 1.
Stealth is more of an oddball in that, while talking and fighting are supported solutions for almost every encounter, stealth only works for like a third. And to get high value out of stealth, your stealther also needs a generous helping of lockpick, computer, critical strike and electronics.
I rather like the stealth gameplay, but playing a sneaker feels somewhat suboptimal a lot of the time.
