I've just come back after a 6month break from WoW. Right now I'm having fun relearning what I use to know as well as adjusting to all the new changes.

I plan on 5 boxing Cata, though I'm a bit nervous about how hard the new dungeons will be to MB.

I'm hopeful that they will require new techniques and skills but with practice most will be doable.

I figure with the rush of folks, I plan to level as much as I can in the normal instances. I figure I can learn the fights, get gear, avoid the crowds and be more ready once I hit 85 to start trying the easy heroics.

Between now and then I want to improve my MB skill, adding CC as an option etc.

I guess if it proves to difficult, I'll move to solo until gear makes things easier.

On the bright side I have so many ways I can get better. I remember reading on these forums about a fellow who brought a new team to 80 and then completed all the heroics (as well as I think heroic dungeon achievement) without relying on all the uber gear. I figure that shows how much more room I have for improvement .
