This forum post details a pretty gnarly exploitable glitch that mages can use to attain 100% multistrike with 100% uptime until you log out. Persists through death. I'm not posting this info so you guys can go out and use it. I'm posting this so you know what to look for. That way if you see this in a pug you can bolt and hopefully avoid retribution.
The bug even persists through spec swapping. The exploit is public and a fix will happen soon I'm sure. Right now warcraft logs are taking down all parses they can find with the bug.
I personally have never been on the receiving end of Blizzard's wrath so I probably sound like the boy who cried wolf but I'm just trying to look out for my guildies. This is not something worth taking a chance over.
So check it out and if you notice a fire or frost mage with unusually high dps this is probably the cause.
Best of luck guys!
