Brand new part needs to be reworked ASAP
Ever since Ruin was nerfed more and more survivors are bringing in Prove Thyself, and even more survivors are bringing in toolboxes. With the only effective gen regression perk being Pop Goes The Weasel, which requires a hook to be able to be used, gen speeds are worse now than ever.
BNP with a standard brown toolbox will get a gen to 50% nearly instantly, pair that with another survivor working on the generator with you and the generator is finished in 30 seconds.
I suggest the BNP add-on be reworked to serve some other function. I was fine with this add-on pre ruin nerf because of the nature of ruin, however now that ruin doesn't affect speed at all, its overkill.
