I still love playing a rogue. Nothing like stealthing through mobs and killing what you need or stealthing through mobs, sapping the ally and stealing that node.

I do find pally, warlocks and hunters easiest to level. Warlock and hunter with their pets and pallies as strong as a tank and able to heal makes things so much easier. As for DK, it is not a point of easy to level but you do start at level 55 so you are already far ahead in terms of levels so it is lesser levelling time.

But I would recommend that you read the synopsis of each class before you choose what class to play. Choose a class that you like. That way you would find that you will be able to live through the levelling process and not get bored compared to end up playing a class that you don't really like and hate the game in the process.

I love druids too.
The cat and bear form is so cute.
Just that since I played a rogue, levelling the druid in cat form always makes me miss not having a vanish button as I seem to always get into trouble a lot.
Can't wait to get flight form though.

Haha thanks. I'll try that. The problem is whenever I accidentally get in trouble, there's like 4 mobs or more chasing me...
