Nerfing fun since the dawn of time. Perhaps it could cause some kind of weird issue in BGs and if so go ahead and disable the speed boosts while carrying the flag or w/e but in a raid? Seems excessive. I can't think of an instance where this was so needed it broke the game or anything it was just a nice little perk sometimes.
Worgan Engineer Warlock here, Frustrating changes are frustrating!
I love changes that cause my Racial to no longer work with my Class talent. I love changes that cause my Profession perk to no longer work with my Class talent. I love the fact I now have 3 different sprints, at 3 different speeds, for 3 different durations.
