What have you had to re-learn in Classic?

I keep popping bloodrage before I try to charge and that doesn’t work out.

I’m finding consistent Tclap use is really helpful for keeping my health going, but also things can go south soooooooo fast.

I trained overpower (requires a dodge to proc) and probably didn’t use it for like 10 minutes or so of questing because I expected it to light up.

Weird one for me is that on retail I set up F1 through F5 to be some interface toggled like character profile, talents, spellbook and I set it up for Classic but I still keep hitting C which is my freaking taunt/D stance/ Shield macro.
