These guys are definitely the real deal, they have leveled characters on my account on a few occasions and I will no longer go anywhere else for business.
They level VERY fast for the time they spend online, though they will not level 24hours a day for safety.
Their customer service is excellent and friendly, and the rep speaks pretty darn good English I must say.
Five stars for this service, if you haven't checked them out they would love to have you as a customer I am sure they will prove themselves to you!
Oh.. and they do not/will not EVER use a bot. Which I found out by tracking my character for the hell of it. They will also run an occasional instance.
They also leave you with a good amount over the gold in which they promise on their packages listing.
Again, try them if you have a character back at 80-85 if you want to pay a cheap, affordable price. (less than $45 if you go through the customer care chat) Just to test them out and they will do an awesome job, I assure you.
Edit: The prices in the original post are a bit off, they will charge you much cheaper if you talk to them! (Good people, just wish they had more business.)
