Eh, I haven't noticed a big difference whether I'm using it or not. I'd say forget it. None of Gaige's game changers are that great, unless you're going full BFF.
I think "With Claws" is pretty decent, but that's in ordered chaos and I'm going down the LBT tree for my new char. I guess i'll just skip on "Make It Sparkle" and use the point in something else.
Should I make a BFF build in the future? Honestly I just love gaige as a character. I've heard a lot about BFF but majority of the time what i hear isn't appealing. Which is why I went with a shock gaige this time around.
