I'm still levelling, so I have a hard time finding a 'fair fight' in battlegrounds, but I've found that when I'm decently geared, and at about the same level, I don't have too much problem killing rogues with my hunter.

The key thing to surviving/protecting yourself against rogues, in my experience, is opening with an AOE. If you can get them visible, they're a lot easier to do things with. Paladins have consecrate, mages have arcane explosion, hunters have flares (and pets to help out if you get sapped), priests have holy nova.

I actually found that -- so long as I had a PvP trinket, I was often able to kite a rogue while holy-nova-ing along, keeping them from vanishing, and keeping myself mostly out of harms way. I've killed a number of rogues that way in Battlegrounds.

Obviously, this is not Arena, and I'm clearly not a top ranked player. None of this means that a twink can't kill me -- and damn fast, often in what seems like only one or two GCDs. However, against a relatively evenly geared/levelled rogue, I've found that with some skill, I can usually do decent at putting up a decent fight.

I will admit that getting out of that first sap offers a huge benefit, and I know that I can't do as well without a trinket. And maybe I'm just succeeding when fighting really crappy rogues. :)
