Something I'm not blaming on the patch but is still annoying is map bugs, it's usually with fear. I was fighting Alliance in Tauren Mill a while ago and this dude from Horde got feared through the map so we had to summon him back with a warlock, he said he was at the bottom of the mesh.
Check out what fear did to me in Battlegrounds today. When a warlock feared me for the second time in Arathi Basin, I ran into a house near the farm and got stuck in the wall for like 5mins.
Five minutes doesn't sound like much but it's pretty annoying in Battlegrounds when the average match is about 28 minutes and the Alliance players surrounded me and knew it'd be stupid to kill me.
Then they eventually got bored cause they were winning and finished me off.
Then I snuck this photo in.
