The above is from the 1.2 patch notes, note the bolded area... i know it is not written clearly, but if does make it available to be parsed now. You'll never get a full endorsement of a 3rd party parser simply because they cannot guarantee the program wont be malware or virus ridden. So essentially use at your own risk.
It surprises me that this is actually being debated though.. They added in the combat log so this parsing can actually be done now... *** would they add in a combat parser and say.. heres the info.. BUT YOU CANNOT LOOK AT IT OR YOU SHALL BE BURNED AT THE STAKE AND CLAIMED A HERETIC....
If it walks like a duck, and it quacks like a duck.. its a duck.. unless your still arguing this.. then i guess its a moose.
EDIT: Forgot to also mention the simple fact, they added COMBAT DUMMYS to the game, and not only just Normal dummys, they also added OP's and PvP dummies also, so no they arnt just there for you to practice rotations... quack.. quack... or *sigh* Moose..
