back in the days where weapons was curated, or we had like 5 maybe 6 perks tops in each row, it was a lot more manageable to keep farming until you got the right masterwork, but most weapons these days have up to 12 perks in each column, and its a pretty well known fact that weapon perks are even weighted on weapons, to prolong the grind for the perfect roll. so having to deal with - twice as many perk options in each row - weighted perks like pulse monitor and other bad perks to prolong the grind - certain master works that can destroy a weapon like blast radius on the mountaintop which will lower it damage output quite drastically. its just too many factors you have to deal with, and I think giving us the option to lessen the RNG checks in rerolling on Masterworks would be very fair. For the right price of course, rerolling a masterwork, is not really something the average player would worry too much about, but for the true grinders I doubt we would bat an eye paying stuff like 40 spoilt of conquest and multiple shards and alloys and I doubt it would bother us in the slightest.
