Wanted to get this done pre U9, but due to my gimpness of Tetherball, Ayspam and I decided to bring out the big guns. I drank 60 or so pots and Ayspam 40 or so. Got it on our 2nd try, I dont wanna discuss the first failure.
Timewise we spent about 6 mins on bases and around 20 mins on the dragon.
Prep each base (djinni and pillar). Ay went to fire, I went to mephit. Killed our djinnis. I winged to ice killed 3rd djinni. Next we each took out our pillar and hi-tailed it to mephit to get the last 1. (this is alot harder than it sounds). Ddoor to middle and prepare for Velah.
For this part we didnt want to get far and find out our dps still isnt enough. So Ay did use the icy prison at the start just so we get an estimate on our dps relative to how much dmg she took vs time spent. This was the only time he used it, so some can call it legit, but I think only 1 use is fair enough. As for tactics, Ayspam nuked (he got the easy part ); myself on the other hand tanked her, spamming dots, and searing lights with my wingman; I also was in charge of kiting renders, watching for breath, healing myself, and healing ayspam all while staying melee range.
Anyway here are the screenies:
