We don't have much time before Cataclysm hits, so let's get down to business. We've talked about some optimal talents for death knights and druids for PvP, so now we turn our attention to hunters. Hunters have always had a tough time in arenas, not necessarily because the class was broken but because the format simply wasn't conducive to the hunter playstyle. It got so bad, in fact, that Blizzard designed an arena -- the Ring of Valor -- specifically to benefit hunters. On the other hand, hunters have always lorded it over in the open expanse of the battlegrounds.
The good news is that battlegrounds will be cool again. Well, they've always been cool in my book, but soon they'll be rewarding cool gear, too. That means hunters will once again feel like PvP gods (without needing the help of an enhancement shaman). There's one big change to hunters in Patch 4.0.1 and that's the change in resource from mana to focus. The difference with the way focus behaves is that rather than a resource well that pays for spells and abilities (mana), hunters have abilities that generate focus in combat such as Steady Shot and Cobra Shot, and then a whole load of focus dumps. In a way it's like death knight runic power or warrior rage without the decay. This means you'll always want to have nearly full focus but never gain focus that will simply slough off because you're over your maximum. It's a careful balance of gaining and spending, although focus regenerates at a steady rate.
