Code:
/focus Aelli
/follow focus
/target Malygos
/castsequence reset=combat Revivify, Flame Spike, Flame Spike, Engulf in Flames
Should work perfectly as long as you have Auto Self Cast on and a button that doesn't dissappear when entering a vehicle. Just keep ramming it and fly around in circles. Don't need to keep facing Malygos either. Just fly, fly, fly around! (Around the area with your guilds healer drake(s), though the range of the big heal is pretty big.)
