I prefer to use the second deadzone listed:
26-35 range
I know they have less out there that can hurt me a lot. Concussive shot can keep them out at that range as well and its a fairly fast CD shot. If I get lucky, it stuns them! Bonus!
If I've been mixing it up with a warrior in Arena, and it happens a lot, Hitash's tactics work well but again, my preference is to keep them at significant range.
Charge doesn't bug me as much because I tend to leave a freezing trap at my feet. They charge, get that one shot in and I run after I'm free or I can trinket out if our healer is down. Scattershot, Concussive shot, wingclips and snake traps do wonders to keep warriors, rogues and paladins slowed down.
One on one, I can usually live pretty long against a warrior and get away more often than not. With any kind of dps backup behind the warrior though, I'm toast. I normally don't have Morris defending me in Arena... he's usually chewing on the healer. So, I can't really speak to any pet defense tactics that might be out there.
I have bigger problems with locks and other hunters... no such thing as professional courtesy among hunters! Sheesh!
