Good bye Dr. Boom.
The beta currently has target dummies implemented in certain cities. I believe thjey have always been there in some form but now you can attack them.
The cool thing comes from a post from Kalgan today: (He has to be good for something!)
"In an upcoming update one of the dummies will be level 80 with normal level 80 mob stats, the other will be a "boss" dummy with normal level 80 boss mob stats.
Enjoy! "
WoW Forums -> Thanks for the training dummies!
Should be a handy way to try out different spec/gear/rotation combinations.
