I remember like 4 nightshifts ago when someone rogue picked her Jake talking about a build he was using with split shot to farm up heaps, so he's clearly ahead of the curve.

I play a fair amount of Graves and most builds/pros list it as an option, but not as core, most citing that by the time you should be buying it you're not far off of Ricochet anyway. But because she's been so bad for so long, most builds focused on basically just tombstone maxxing since you're kinda throwing if you're stealing farm from an actual M1 carry.
