I found it [much] easier to do the Empyrean than the WoE weapon. At worst you have to deal with asshats camping ??? or outclaiming a 10min respawn Heqet.
If you're serious about Corsair, and got some dudes who want WoE weapons anyway, just opt for an Empyrean rotation (Fullfill your obligation to eachother though) and spend a little more time for ten times the power.
