The trick with a survival hunter all centers around traps, and melee moves like wing clip, deterrence, etc. A very good, viable Survival hunter combines 40 points in the Survival tree with 21 points in the Marksmanship tree, gaining Scatter Shot. This not only shines in PvP situations, but works in PvE as well. Scatter Shot is a lovely kiting tool, buying you time between Wing Clips, frost traps, and concussive shots. You can also lay a Wyvern Sting on a target if you feel like stopping to bandage up. While they sleep, you bandage up.
Much can be said now about a hunter who invests at least 41 points in the Marksmanship tree. Blizzard has finally gotten around to repairing this tree and I'm quite satisfied with the results. Silencing shot is now actually worth having, and now a Marks-specced hunter will individually do more ranged damage than a Beast Mastery-specced hunter. I always had a problem with that before; it made no sense whatsoever to spec Marksmanship when the same hunter, fully specced in the BM tree, actually did more DPS than if he/she were fully specced in Marksmanship. My own hunter is specced fully in Marksmanship with the remainder in Beast Mastery, to pump both himself and the pet up a bit, and to gain the lovely Focused Fire talent, which gives you +2% to all damage while the pet is active, and a +20% chance for the Kill command to crit. Every little bit helps.
Re Paladins: I'll choose to disagree regarding the DPS of a Ret pally and an Arms/Fury warrior *if* the Ret Paladin in question stacks up on spell damage. Crusader Strike can hit for gobs and gobs of damage if a Ret Pally has stocked up on his spell damage. With the Retribution Aura active and a consecrate running, the damage starts to add up quickly, and not just on one target. With all of this said, I personally feel warrior DPS is more stable and dependable in PvE than Pally DPS. IMO, a Ret Paladin is ideally suited for PvP and is much more iffy in PvE. I have watched Ret Pallies decimate players in PvP enough to know they are not to be underestimated. The stuns, judged seals and Crusader Strikes can wipe the health bar of the beefiest locks and warriors clean in no time.
