PvP nerf/ translation error?

Hi, reading an update (which probably won’t come out this week, but probably next), I saw that the gs gets a little nerf. Quick step and … Stampede. I play pvp arenas, and my 2 characters are gunslingers, but I don’t remember that this class has Stampede skill. Now the question is, is it a nerf for a different gunslinger skill or a different class?
