Some example clear times:
Abiesfir, Level 160 Priest 100/Druid 40 (from before priests got zerk stance)
- 24 minutes (Melee only)
- 16 minutes (Polymorphed using Flame Strike to proc VOG staff)
Abiesfir, Level 212 Priest 100/Druid 40/Monk 60
- 13 - 14 minutes, both Melee only and Polymorphed VOG clear times
Takeaways: Zerk stance was huge for priests. Also, I was very surprised to find that VOG spam didn't have a faster clear time than melee at higher level, but that's probably because Flam Grav can be hard to aim, especially against stragglers
