Just specced 35 Regrowth on my bard and it said I was getting a yellow spec group heal at the trainer however I don't have it. I had the same issue with the blue one a few days ago but I kinda shrugged it off. I am not sure if this is only on bards or if Druids have the same issue. Kind of a big deal for PVE mostly.
