Question for starting a rogueFollow

I personally have played the above mentioned classes and more. I LOVE my rogue. It is alot more fun than any of the classes you mentioned imo. The only class that I think is more fun is a druid. As for leveling, rogues level faster than any class that doesn't have a pet. Although, leveling depends on the individual. As fas as leveling specs, check out Theo's Rogue Compendium. It has all the info needed for leveling and such.

Druid after 20 lvl is not slow anymore (cat form at 20lvl). Druid is hybrid class, you can play as a tank, dps or healer. Rogue is just dps class, but it is very nice to play.

I find shaman interesting also, and after 40lvl he is very fast in lvling.

I have a 70 druid and loved playing her, loved everything about it. I tried a rogue quite a few times but really struggled. While most classes are relatively easy to get to 20, I usually gave up on a rogue way before that because I got sick of dying. You're squishy and other than dodging, you don't have a lot of ways to avoid mobs. Hubby kept telling me, if you can just get one to 20, it's a whole lot different... and he was right. Now she's 47. :)

In my opinion (one that I know a lot of people don't share) rogues are a bit more complex to play than druids. You have so many abilities it's hard sometimes to choose one. You have to know what the right finishing move is for the situation, how to handle mobs that run, adds, and when to use vanish (only if I KNOW I'm going to die.) But I absolutely LOVE playing her. She is a complete blast, and whirling fury of blades that kill things quicker than anything I have ever seen. I think I like playing her almost as much as my druid...
