Good stuff fellas! Reppin' for the Pubs! Now go get Revan!
Yeah this is a tough one to answer. To me, it doesn't really make much sense... and tracking in general for all of the separate operations would just be a pointless headache. Though, to answer your question, I would most likely do whatever it is the majority of the guilds would like.
Unfortunately not. Even though I have been a bit relaxed about what I accept (mostly due to the state of the game/guilds/players viewpoints) I feel that a combat log wouldn't be very telling. I need to be able to see all members of the group, see that they are all apart of the same guild, achievement, loot..... blah blah....
