Remembering old stuff while also being the only Version of WoW where I actually listen to the Ingame sound, rather than some spotify or youtube playlist. Also still discovering new things like in some Bushes in Ravenhill in Duskwood, there are blinking eyes - spooky I tell you!
Never actually enjoying PvE myself, I would never say no to a Zul'Farrak run - by far my most favourite!
The highest Achievement I feel is leaving Barrens with every Horde Toon I make, trying to reduce the sanity loss as good as I can.
