Kill all 6 pillars at roughly the same time, bring all adds and entire raid to the start of the encounter (the terminal thing).
Pop a raid CD if absolutely necessary, but preferably a small one (boomkin tranq) while avoiding blue zones and light aoeing as you want the tanks to have a ton of threat.
The second the floor spawns have the entire raid move onto the floor and spam AOE stuns, push backs, CC's while nuking the remaining adds. Being on the floor gives you the damage buff which helps level out the adds pretty quickly.
Other than that we found if one side was a lot further ahead on pillars to immediately start killing adds, or at the very least dotting them so they were low when we moved to the console.
Due to the enrage timer we felt it was almost unkillable last week but this week using the above strat we killed it in somewhere around 7 pulls.
Hope this helps!
