Hi, found a decent exploit for during arena.
While in arena:
-Disconnect yourself.
-Relog in.
-All cd's are resetted.
Had a mage ice block 6 times in a single arena match.
For mage's it's nice to use invisibility before you d/c yourself.
A fast way to do this is the following:
-Have 2 wow's on.
-1 wow you play on
-Other wow you have all your details entered into
-While you're in arena and you need all cd's back: alt-tab, press enter two times, and you're back with all cd's resetted.
Enjoy.
