The most "efficient" way to do this is far easier than everyone keeps making out.
The dragons down below have either no respawn time or an amazingly long one (more than 4 or 5 hours).
The absolute best way to do this is clear away the dragons that are around the platform Zolo is on. Pally tank him and move your pally to the edge. Have a lowbie down the bottom do something to get onto zolos aggro table (a heal, ranged shot on him, anything).
The lowbie is now on the aggro table of the boss and wont get off until they run out of range, die or the boss resets.
Don't use consecrate, it's pointless, put max rank blessing of sanctuary on, devotion aura.
Cast Seal of Light and make a macro with the following
/target atal'ai skeleton
/startattack
then just press the macro and keep seal of light up.
When the boss is low on HP, bubble yourself. Zolo will target the the other person down below who is on his aggro table and then evade bug back to full. When his health is full again, right click the bubble off (sometimes he will reset if you leave the bubble on but it's easy enough to pull him again) and he will start beating on the pally tank again.
Grats, you now win at ST powerleveling.
Just a show of some easy positioning. Lowbies can jump from the top against the wall and land on a ledge then skirt around underneath.
