Having not made a new video in a while, I thought I might as well make use of this footage I recorded. It demonstrates how 2 mages can, very quickly, clear Heoric Ahn'Kahet. Once you know what you're doing, it can be done in 10-15 minutes rather easily (most of that time is just spent waiting on cooldowns). Of course if you have enough DPS to do it, then you probably won't need any of the gear. But hey, it was sorta fun and it sounds cool too!
Standard Arcane PvE spec and 2 mages is all you need to try this yourself. A list of songs is included in the video.
