We used a strategy we saw online an instantly knew this was the one. We tried it, and downed him on the second attempt and have only wiped perhaps 4 times out of the last 30 or so. If you have a good rogue that kites well its quite simple.
Jave a 3 man rogue kiting rotation, all need speed enchants on boots, and have a few extra speed pots.
start off by having a rogue get the orb. Razer then kills eggs until all warlocks and controllers are down, in the meantime split up the rest of the raid into all 4 corners and kill any mage only you see. dragons are slept by druids and picked up by hunters running in a circle around the room. If somones getting beat on by a lego or dragon call out for a sleep opr a hunter to pull the dragon off. if its a legion, run or sheep. (you only need to do this for a few short moments) Heres why.
Once the controllers are down, your 1st channeling bar for razer should be nearly up, have the 1st rogue Reget the orb, and then run around the outer perimiter of the room. Razer has Massive HP and can run faster than anything,. Use that to your advantage and cleave any stray mobs (legos and dragons) and Everytime Razers AE fireball is up launch it to get aggro on all the would be strays/sheeps, etc You do this for an entire bar almost. Near the end of tjhat bar you should have most mages down, and nearly all of the room running after razer. Have the rogue release him, and a backup rogue take the orb. The backup rogue will kill all the rest of the eggs till one is left then he hands orb over to the Main tank to get aggro after the last kill.
a priest will run with the rogue shield and renew if needed who now has the entire room nearly on aggro train and he runs around the outer perimiter cutting corners by jumping off the stage if possible to gain a lead. Should the mobs start to catch him, hunters lay down a frost trap to slow them a bit or warriors shout. It is usually a 2 min red train of death thats following maybe 1 rogue and a ew strays you can eliminate. Easy pickens till phase 2 where all healers are max heal range from, tank and Offtank. priests get one tank druids shammys get the other, the meelee bandage the healers for the random firball he may spit out.
should the rogue kiter die, number 2 in line immediatly AE'as and gets aggro back on razer and releases it to backup #3 and now 2 is the main kiter.
Its actually pretty funny watching about 30 people stand around doing nothing as maybe 10 kill strays and all the red is trained on one man.
If you get it perfected, razer is a cake walk. But as always each guild has strnegths and weaknesses so do what fits your guilds style.
Here is the video we based it on.
