Stats for Outlaw Rogue

Icy Veins and everyone else tells me it’s Crit and Vers. Does that mean I only want gear that has Crit and Vers. Because when I look at sites like IV it shows that my BiS has stuff like Crit and Mastery or Haste and Mastery and I know there is gear I can get elsewhere that has Crit/vers.

There is no stat that’s BIS anymore. Only way to find out what stats are good for you is to sim it
