similar thing happened to my shaman alt, suddenly hunters are skewering me like ******* and half of my earthshocks are resisted (only the earthshocks it seems, no idea why). Oh, and new rockbiter sucks, all I've got to thank for is the 30 minute weapon enhancements which are nice not to have to recast so often.
Also, EU server's have been coming on and offline like they got a bad case of schyzofrenia and apart from suddenly getting the 15 minute countdown once in a while cutting off your gaming, I've had to put with and invasion of french, english and german in my spanish server spamming all kinds of crap everywhere and even behaving rudely (yeah, UP YOURS ************* besides taking the servers population from low to full in less than five minutes and causing me to disconnect and have to wait a ******* queue ! aaarrgghhh !
(most EU server's still down at this hour, piece of ****)
