Ergh I quit WoW just over a year ago... Once I got the legendary healing weapon, the grind for it absolutely killed it for me was a shame as I was in the top 5 for best geared pally on Blackrock...
Stupid me downloaded WoW again on the weekend.. Waiting to get the authenticator removed off my account because I can't find it... Is the xpac any good though? Can you actually play casually now or is it still a grindfest?
