There's nine or ten of the orbs floating around Vortex Pinnacle, and the only ones that you need to deal with while in a group are the two that require being knocked into the air during the second boss fight.

Most of 'em can be gotten just running around the instance after everything is dead.

For pardon denied, my group comp( I had already done the ahieve, but I don't remember the composition of that group so I'm useing my most recent success group). We had a rogue, warr tank, mage, a spriest and a shaman healer. Plenty of interrupts, so we got it on the first try.

It's not even that hard. Just wait until your group is done with the instance and go back to get them. Every one of the orbs can be obtained by jumping from he correct locations.

Pardon Denied is MUCH easier with a Death Knight tank. If you time it well you can AMS Asphyxiate and remain at full health throughout it. DBM timers seems to be a bit slow though, so if you pop AMS right before it says asphyxiate is coming up it will fall off before asphyxiate is actually cast.
