You can't exactly blame them for posting about them, Muffin. Hunters and Pallies are the classes that have had the most notable changes so far in the latest patch. Ret Pallies are killing things a whole lot now and becoming hugely popular throughout WoW, while Hunters got new pets with new talents that require a different approach to master. What was a good pet last week isn't as good this week [Cat] and what wasn't a good pet is so popular now. [Gorilladin]
You can't blame WI for posting more about them in the first week or so. If they keep posting them, then sure, that'd be a problem...

And no, there is no logic in complaining about too many Hunter topics in a Hunter column. All he's done the past few days was post in Hunter topics complaining about it. It's not helping at all.=/
And yes, even though my main is a Hunter, I wouldn't want this place to be Hunter central. I got BRK to read for that and such. But I'm not going to complain when another class gets more topics later on. Especially not in their own column.
