Recently having hit level 61, I've had my rogue sitting in lobby and I've noticed that a good portion of buffs simply are not sticking to him or his merc. The mbg's are hitting them both because I see the spell particles land on them but the buffs just don't show up. I have plenty of room left in my buff window for buffs (15 buff slots + 2 additional from AA's) and there is nothing in my blocked buff window. Now I'm not missing all mbg's as I have received a set of shaman buffs and brells. However, I've noticed that the buffs that seem to be landing are all from the HoT expansion. So my question is: "Are the new expansion buffs restricted by anything such as character level, not owning the expansion, and/or account tier?"
