Sorry, but that's total bs in a duel setting with the range limitation. I don't care how much you think it's true, it's not. Homerjay is one of the best hunters on this realm, and he says in his guide "5. Kiting of melees. In theory it seems pretty much impossible to kite a warr right? He charges you --> disengage --> intercept --> gg." And he's talking about arena, with a greater ability to kite. There are strats for dealing with warriors, such as having a ravager pet by your side who stuns the warrior when he intercepts, but it's a tough fight especially with all the burst warriors have on this server.
I'm not saying a good hunter can't beat a warrior, he can, but your statement is total bs. If you think it's impossible for the warrior to beat a good hunter in a duel, then you're a bad warrior, end of story. If you want some video proof, he's Swifty beating a retail arena master hunter in an open-world, full range environment, even though the hunter used rocket boots:

And Swifty didn't even have a tree to hide behind (and the hunter didn't have to stay close to a duel banner)! But wait, this can't happen according to you. My bad.
Warriors lost intercept in Cata- I would kind of agree with you then. But just by pressing his charge and intercept macros, which is really easy to do, the warrior puts a lot of pressure on the hunter with the automatic stuns.
