I've said all this in another post... but I firmly believe that KZ would be EASIER for a single player to box than a raid to handle.

However - you could NOT accomplish this with the common 4+1 team style that boxers are so fond of. You would need a somewhat balanced raid.

I'd try this Boxing build for 10 man raiding:
  1. Warrior - Prot
  2. Paladin - 20/41 holy/prot
  3. Priest - Holy
  4. Priest - Shadow
  5. Mage
  6. Mage
  7. Mage
  8. Warlock
  9. Warlock
  10. Warlock


Attunemen - Simple tank and spank fight - with a properly geared tank you can single tank it - if you are using a paladin or bear for your MT the multi-target threat gen is perfect for this.

Moroes - Simple Tank and Spank + Control fight. Setup your two shackles, pull with the paladin, split off Moroes with the warrior, chain shackle 2, kill 2, kill moroes. You can then walk out of the room and let the shackles reset if you like. You have bubble + 3 soulstones for handling the Garrotte, bubble will be reset before the 2nd soulstone is needed, so thats more than enough to handle the full fights needs.

Maiden - Simple tank and spank fight - positioning is important but accomplishable. Put the paladin behind the tank - spread everyone else out facing in with a single key bound for moving forward - it's a symettrical room so everyone could move in the same distance from the wall.... Three dispellers for the holy fire, paladin to heal through the stun's with blessing of whatever the fuck hurts the paladin when the warrior gets smacked...

Opera - R&J - Split tank tank n spank - ezmode.

Opera - Oz - Lots of fire and fears help here, use the control character to move the tin man around, keep a mage firenuking the strawman with a focus macro, keep a lock fear + dotting the lion, kill Dorothy, Kill dog, kill the rest as you desire. Hit your follow macro and kite the Krone around the room without getting hit by the vortex.

Opera - Big Bad Wolf - This fight you would HAVE to be johny on the spot with running and would have to be able to switch which box was under control but still throw heals from all boxes on the right character... Other than that, it's a point dps fight.

Curator - Zomg 3x COD, 3x Trinketing mages Evocates would DESTROY the guy... all that point dps on a guaranteed /assist would devestate the sparks better than any group could imagine. Eazy fight.

Illhoof - 3x warlocks 3x healers + LOTS of dps = ezmode on this one. Chains will die nearly immediately again because of the point dps NEVER fails to assist.

Shade of Aran - You would think this would be your hardest fight... you would be wrong. IT takes a LOT to get 10 people to stay out of the blizzard, to stop moving on the flame wreath etc... but one persons easy to control. DPS would be great, you would NEVER waste an interupt because someone else had just used theirs... when the adds spawn you have point DPS to destroy them quickly... everyone moves as a pack... ezmode.

Chess - Free Epix

Netherspite - This one WOULD be hard because of the positioning - I'd personally swap two locks out of the blue beam using lifedrain, and I'd swap the warrior/paladin between the red/green beams for tanking... but definitely accomplishable.

Prince - This fights about positioning - slap his ass on the far wall and get everyone in the right spot and no one gets infernaled... then it's healing and DPS.

Nightbane - This fights about having control over the dragon (warrior tanks) and the adds (Paladin tank + 6x AE). Easy as hell.

So, ten boxing KZ is definitely possible, the fights aren't impossibly complex.

I don't think that you could 25 box say Gruul's Lair - however on that same note I'd wager that 5x5boxers could dominate raid content better than any 25 individuals in most cases.
