I don't see how it's "dirty". And not everyone needs them; I haven't used one yet and have a 50 and a few 30's in a timely manner. Plus, on my server these things were dirt cheap. Cheaper than they ever should have been. Major experience boosts were 5k for a while. If you have the money, why not corner the market and make some extra stuff. From my experience, no one buys them over 15k for a single one anyway. Even if they are listed that high, people are usually pretty quick to undercut. I mean, people are always auctioning boosts off. I have trouble believing he can corner the market on them for any substantial period of time.
