The short version of how I do it. Buff! All normal player buffs benefit your drakes. So mount up in reverse order of buff importance that way you get all buffs on your lead drake at least.

I use either the 5 emerald method and use autorun on all 5 in the fastest succession I can and just alternate between windows turning left a little bit at a time while spamming dps keys. Then when the orbs need avoided you can just stop turning til your safe or turn outward or whatever your ok with.

The faster way is to take 2x red 2x amber 1x emerald. Get them all lined up the way you want them while below the boss and then just broadcast your jump button til your high enough to engage. Get the hang of the skills you need to use on trash and it's pretty easy once you engage. Never move just keep broadcasting all keys on all windows then when the orbs come keyboard turn 180° and run like hell. When you come back, keyboard turn 180° again and come back and repeat. usually you can get 'close enough' with the broadcasted keyboard turn to be safe and oriented properly on the boss.

Right now I'm working on the strat of park your team on the loot chest platform and engage the boss with 1 red drake and 4 players with no drake. Groups can probably do this fairly well with good mana conservation as the one ruby drake will benefit from all group buffs and totems and you can easily heal through the boss with one well geared resto shammy. Have yet to see whether the phase out will obliterate all your toons as I try and steer clear of that instance anymore.
