WINGIT: Tempest Keep Terminated

We have long been trekking into Tempest Keep and slaying the bosses whom dwell there, although Kael'thas Sunstrider has always stood firmly in the way of us clearing the entire instance.
We did take the time to try and 5-man the fight but even then we didn't manage to take him down.

Well now we're 85 and we hit like trucks, went in downed him.
I personally am desperate for the [Ashes of Al'ar] so I'm incredibly over the moon that we are now able to get this boss on farm! Soon I'll be flying though the skies on fiery wings. ^^

Here's the killshot! Click for fullsize as always :p
