I hope so. Would be nice to have that 30% extra crit damage.
Not in my experience. I’ve picked up 3 B-tches in various playthorughs, and it still is a bit underwhelming in damage. I still fall back (in non-elemental SMGs) on a Stinger for the type of max pinpoint damage that the B-tch gives me in BL2, but not in BL1.
