Hi!
Cataclysm classic. Fire mage. Not my only one. Tried turning off all addons. Checked flying skill (shouldn’t matter since it also happens when I’m dead)
I’m flying slower on ONE character than all my other characters. Happens to be the one I play the most on. This is also the one I’m digging with meaning I’ve lost a lot of time flying slightly slower than everyone else. This is on all flying mounts too. and like I said while I’m dead flying too.
