Why is there a major glyph of feint?
Basically, rogues have relatively few abilities, and we were desperate for something that wouldn’t have serious PvP balance ramifications. I agree this might be a good candidate for a minor glyph. Remember that we are going to be adding a lot more glyphs over time. You shouldn’t view this as one of your very few useful glyphs is less useful, because you’ll eventually have a lot of choices.
