So this is my thought. Im playing around with Burst of Speed since I now have a tank set as a mut rogue for BG's and RBGs when I decide i want/need to flag carry. What better ability than BoS and with the buff coming in 5.4 to BoS, it's a must have for rogue FC's. Anyway i realized that BoS doesnt replace Sprint. What is the point of having both? Heres what I propose:
Make Shadowstep baseline. When choosing BoS have it replace Sprint. Put Versatility back in (previous lvl 90 talent) in place of the Shadowstep talent and take away the versatility glyph coming in 5.4.
