"BRK is a hack, and if you read the hunter forums you'll see that many hunters agree with this, including the top-listed arena hunters, raid veterans, and other players who are familiar and comfortable with their class and do what they do very well."

Raid Veterans:
Does my opinion as a raid veteran count? I disagree with them. I admit, i'm mostly a druid and my hunter is only a Kara-running alt. Still, i think i can safely say that name-calling like you find on the WoW forums is no match for solid data like you find in his blog. There actually -are- posts of value on the forums, but what you described is merely fruitless name-calling.

Top-rated Arena Huntesr:
I'm pretty sure what the "top-listed arena hunters" say is quite thoroughly irrelevant, as BRK's columns are generally about PvE, not PvP. I could call V'Ming a hack (just as an arbitrary example -- i don't actually dislike his stuff), but my credentials as a druid don't lend much to my authority on the subject of warlocks. I could call Big Bear Butt a hack if he starts talking about PvP, but my experience as a raider means nothing when it comes to PvP, so i'd be entirely baseless to do such a thing. The same goes for "arena hunters", as you put it.

Other People:
Casual players? Priests? Why would they get involved? I think you're making that part up.

My Opinion:
I find his writings to be very informative to those who didn't do the painful research of reading the WoW hunter forums before BC, like i did. It's much easier to absorb his advice on the BM spec and general hunter tactics (he doesn't go into detail on SV and MM), backed up by data and instructional videos, than it is to work out what the hell hunters are supposed to do by reading the flaming pit of feces that are the WoW forums.

Some people are offended by his writing style. Why? Are they upset that he would come at them with data that doesn't agree with their bias and then present it without obeisance and temerity? Do they think themselves worthy of greater respect because they hold dominance over outdated facts? Do they think he insults the SV and MM specs, despite the way he completely /doesn't/? Are they afraid their e-peens are going to shrink when they see another WWS post with his damage output in the number one position?

Maybe what's most offensive is that he's correct, and they just can't stand to see someone be correct about something they don't want to hear.

Seriously, i haven't heard a good argument against BRK's writings. The closest anyone has come so far is, "he uses 'we' instead of 'i', and that's unusual, so i hate it". Most of it is just "BRK sux".
