If you want a challenge, and if you're set on playing resto druid, don't go all out 24 fully enchanted. Try going with f2p restrictions. You're going to faceroll as a 24 resto against f2p's. You have to remember about 70% of the f2p population isn't even twinked properly to OUR fullest potential, much less being able to compete with fully enchanted people.
Just seeing that this was made a week ago tells me you probably already know most of that. I won't argue anything, just simply telling you that's not going to be a remote challenge, or if it is, nothing compared to what it would be as a f2p.
