I have been soloing this boss for a while with my fury warrior, and no one believes it, saying that boss is impossible to solo.

In realty this boss could not be any easier.

The things you need:
-Titan's grip
-Any Shield
-T10 protection 4 piece
-Bryntroll

Phase 0:
-kill the 3 mobs on the left
-take the orb and destroy as many eggs as you can with the 4 key

Phase 1:
-DO NOT KILL RAZORGORE
-wait out the debuff, so you can mind controll the boss again
-spam Demoralizing Shout
-spam Thunder Clap
-when debuff is gone, walk up to the orb, bloodrage, and take out eggs as long as you are above around 20% HP
-under 20% HP right click the pet frame under your character frame, and dismiss, then Thunder Clap instantly (thanks to Bryntroll and the uncountable amount of adds, you will get full HP from that)
-repeat

Phase 2:
-keep up Demoralizing Shout
-single target dps Razorgore
-keep spamming thunder Clap
-survive with deff cds the 8 to 12 sec fear + stun or just soak it if you can
-kill Razorgore and the adds after

As an example, I killed him, forgot Ragnaros talents on:
