Cynwise at Cynwise's Warcraft Manual is playing his warlock. He writes
I want to enjoy playing a Warlock as they are now, flawed yet challenging, before they go away.I can understand this sentiment. For many, it's like their classes are changing so much that it's not the same class. Even if the changes are for the better, it can be hard to accept so many differences from the character you know and love.
Personally, I'm impatient. Now that I've seen what's up in the MoP beta, I want it. I want it now. I love my red panda and mistweaver monk, and I don't want to play anything else. I think that my attitude is unfortunate; however, as I'm not taking advantage of the game I'm paying for as much as I should.
Are you savoring the now-ness of your main? Will you miss your class as it is? Or are you anxious for the changes that will come in Mists of Pandaria?
