This is pretty much a stealth brag post I guess, but I've kind of ran into a somewhat funny issue.
I've now picked up all of the Legendaries for my main Rogue spec, Outlaw. I've been using sims to see what two are best, but also decided to spend some time on target dummies as well. After a bit I realized that it's kind of pointless to do my own testing. With how Roll the Bones works, it can easily heavily influence how well I perform during that short test.
So the moral of the story is, bad RtB rolls will kill my DPS regardless of whatever I use, so I'll just use the two that I want to.
Now I just need to decide which loot spec to switch to for my last Legendary.
