My take on this:

Rogues:
Totems - Stoneskin, Earthbind, Searing (later change to Nova), Healing Stream, Poison Cleanse, Wrath of Air
Spells - Frostshock, Flame shock, Chain Lightning, Lightning Bolt, Lesser Healing Wave, Elemental Mastery & Nature's Swiftness
Tactics - Drop Earth & Fire Totems 1st. Frost shock & Flame shock as an opener. The idea is to slow the rogue down as much as possible and allow you to get off CL's in between shocks while the searing totems eat away their health. The dot from Flame Shock and the slow from Frost Shock & Earthbind should hamper them from using vansih / sprint to get away. When they pop Cloak Of Skillz, drop your fire nova totems. Fire Nova has a 5 sec cooldown (untalented) which is also exaclty how long CoS lasts - it gives them a nasty surprise when the come out of it! Also have a healing macro set up that has target=focustargettarget in it - that means you are automatically healing whichever toon the rogue is targetting. Elemental Mastery +CL is good to use early to force them to pop CoS. Save NS for trying to shoot down fleeing rogues with either CL or LB.

Warriors:
Totems - Tremor, Stoneskin, Earthbind, Nova, Searing, Healing Stream, Wrath of Air
Spells - Frostshock, Chain Lightning, Lightning Bolt, Lesser Healing Wave, Chain Heal, Elemental Mastery & Nature's Swiftness
Tactics - Tremors always go down 1st because any smart warrior will try to use Intimidating Shout to fear bomb your group (use trinket if necessary). Warriors don't tend to jump around as much as rogues, but you still want to keep them slowed to give your LB/CL time to cast while they are still in front of you. If they are focused on one target, use the same healing macro outlined above. If they are tyring to hit multiple targets with Whirlwind, Cleave or Sweeping Strikes, Chain Heal instead. A timed Elemental Mastery +CL and exploding fire nova, followed by a shock should wipe out most of their health or kill them outright. Use NS+EM+CL if they keep running behind you.

Hope this helps...
