Cataclysm is changing the game dramatically. We will have to learn new builds and rotations, and learn how we mesh with other roles. As WoW’s meta-plot advances, our RP is subjected to equally dramatic changes. And to be fair, all of these changes may be a bit overwhelming.
The best way to handle changes this big is one aspect at a time. The aspect to work on first? Enjoying the game. If you want to work on the crunchier aspects of WoW and hit up the target dummies until you’re pulling the proper DPS or practice healing with a ton of pugs? Do it. If you want to spend your nights getting the RP back in order before Deathwing ruins everything? Do it.
What do you need to get back into the swing with WoW? Is it something you can take control of, or is it something that needs to happen in game?
