I think droods must be one of the hardest class's to play at low level, *by low level I mean lower then 30 or even 40. Maybe only second to prists imo. *Every class has its problems at low levels though. I wanted to delete my rogue at lvl 15 coz i though rogues sucked, he is now 67 and i love playing on him.
My lowest alt is a 29 drood and I really battle with him at times.. the biggest thing pushing me on is the travel form at 30 and how good droods are at 60+
Stick with the drood, you won't regret it in the end. Droods have got a lot of loving since TBC expansion and are now one of the best class's in the game, being totally feasable in pve, pvp, healing, dps or tanking.
Damn... now I just want to go home and work on my drood... thanks a lot!
