What are the most important things you want to focus on during delve? Like I know you have your indi spell on dd or mages. But for your loupan couldn't you have the mits for -dt on loupan and I was reading somewhere that any pet -dt also works. CCouldn't you augment the selenian cap for more -dt or does that even matter????
I'm still not convinced the pet:pdt working with loupans isn't a bug created by making the AF hands in the first place, so I'd say only (re)augment the cap that way if you aren't using it for something else.
As for Delve, it really depends on which Geo you are: Up front with the mob or in back. Up front you should worry about your two geo spells and keeping yourself alive. This includes making sure Phalanx is up and reapplying RR asap if you should happen to die. In the back the Geo can be called upon to haste a sch. That's as or more important than the Geo spells themselves.
Of course if the alliance leader asks you to have something else as priority do that too, and be prepared to switch roles if one of you dies.
This was mostly pre weapon update that added skill so it might have changed somewhat, but you get the idea.
