Powerleveling: Its a logical assumption. Generally people reading guides are building their first toon. And from what I have seen, people are obsessed with leveling to 70 above all else, I have come across many people that hadnt even chosen professions until 70 (many). They made the statement is slows your levelling, which it does, simple as that. With regards to the ads, yes, we all hate them, but unless your all donating to the author to help them pay for their time and hosting etc, you will have to put up with them.
