I have currently Surv and BM as my 2 spec my stable currently includes 1 sprit beast. I have noticed when im using stampede without the glyph, I only get 4 pet and when using it with the glyph, i get 5(of the same kind obv). I can't really tell, for some odd reason, if this impacts my dmg or not, or maybe its just a cosmetic thing. Does anyone know?
