these spells do drop from the higher tier VWs. I know people who has gotten a Comet off Qilin the other day (no daggers/boots though).

I usually only do WoE on Sat/Sun morning (EST) which is peak JP time when there are around 100+ JPs in there. Otherwise, weeknights are just a crapshoot and usually just a waste of time to go in and sit and wait for ppl.
