Here's an update- the character is leveling fast, but I have concerns about how they are leveling it. The armory page says the character has completed no quests, and she has crappy gear. Also, the character is on for very long periods at a time. So I'm concerned they are botting it. I told my concerns to the company and they said they were using the recruit-a-friend program and that it would be faster. I told them I want safety, not speed and that I wanted to see quests being done or I would change the password and not do business with them again.
So at this point, I prefer xmanlevel since you can clearly see that a human being is doign the leveling. I just don't know whether that's the case with this one. I'm going to track down the character on my server and watch what she is doing in person to see if she is being botted.
