I actually don't have any friends who do WOE, and I have Hiradennotachi+2 and I am holding 20/30 Advancement, 11/30 Glory, and 13/30 Birth. I got those in about 2 weeks of doing WOE for about 2 hours a day. I wouldn't go so far as to claim Kannagi (90) is easier to get than Tobi+2. I admit WOE drop rates suck and it is time consuming, but 30 coins + Crests you have anyways is much much easier than 175 NM drops. You can't compare soloing in WOE to not soloing your Kannagi drops. If you were soloing all of those NM drops, it would take you ages. All you need to clear Flux #2 is 3 competent NIN/DNCs and a sac puller. On my server, there's usually 5 or 6 people in WOE at any given time, so there's a lot of teaming up. I've heard in some servers it is deserted, so that could make it more difficult.
