Hi,my name is Stefan,though you can call me Steve.I never played on this server before,but I have played wow before,yet I am still pretty much a noob.Now,I have decided that I will play wotlk,though I have not yet decided which realm,because I don't know the rates on either one,so if you guys could tell me,that'd be great.I'm probably going to play dps,since I never played tank or heal,I haven't decided on the class yet.And I got another quick question,I read on reddit that this server has a lot of bugs,though the posts were several months old,from the beginning of 2015,is everything okay now?
The rates of Lordaeron are x1. Deathwing and Ragnaros are both x7. I'd also recommend reading reddit with a grain of salt. Lordaeron is the most bug-free server of its kind. If you want to avoid bugs as much as possible, I highly recommend that you try it. Deathwing and Ragnaros will be updated with Lordaeron's core later in the future.
I hope you have a wonderful time. Best of wishes and have fun!
