WoW has been freezing up on me since 4.2 was released. I log into my main only to be hit by very low fps to a points where the game stops responding. Tried playing on an alt in LFD - I got into a dungeon and froze up like on my main. Here's the laptop I use: http://www.newegg.com/Product/Product.aspx?Item=N82E16834220870&cm_re=asus_n73jq-xv1-_-34-220-870-_-Product I use ElvUI also so that may be causing the issues, but I really don't want to get rid of it.
Stop using addons, or update them.
