Good news: VW drops aren't pooled, so you aren't really competing with other people. Bad news: That doesn't help the drop rate. Good news: STR Thokcha is basically equal with Coruscanti. Bad news: Flame geodes.
Also, I just attempted Feuerunke. My crit high was 13, regular hit high was 7, highest exenterator was 75, Aoelian Edge is the best damage source, game froze about halfway through. (All 5 of those are peeves.)
