I've long reached the point in GURPS where I can imagine a creature and spontaneously ballpark what rolls should make it succeed at what action, closely enough for table play. That's ridiculously faster than adding seven barbarian levels, and more versatile.

That said, I'll inform my players after a few rolls that "They have just 7 ST", and "it's Block is, like, 15!", as they should start to guess. I'll also give rolls to know or guess these things, as appropriate - I'm especially generous about revealing resistances and hinting at vulnerabilities, because using an unusual for of attack is pretty much always way more fun than killing everything with raw damage.
