Sally is correct on the AG issue. Cata, you and Keal and others were holding on to those AG pops for a couple of weeks because we have been focusing on the
other T3 mobs in the Tinnin path, Dea and Gotoh Zha. If you look at the attendance posts from April, we had already done a round of AG's. So the "waiting" is not caused by any inherent inefficiency in the ZNM planning. In fact, the more that I move the ally to different mobs in the same night, the MORE inefficiency results. That is why I made the call for the ally to stay at AG last night, even though I knew full well we had Gotoh pops to burn through. When I set the LSMES, I had originally
planned to move to Gotoh, but when everyone and their mother started showing up with AG pops, it was simply more efficient to keep everyone there.
(On a side note, I know people started grumbling once I called priority on DK and Lenus's AG. Because of the sheer number of AG pops people started showing up with, I let priority slide until DK and Lenus reminded me that they needed 1 AG apiece to complete Tinnin. That has always been an established priority rule during ZNM night. The rest of you certainly got enough chances to /random before and after DK/Lenus popped theirs.

As for your other suggestion, as Ryan said, the issue here is that when Muir and I first started setting up ZNM nights for Anduril late last year, we would typically start the evening at 8 EST only having 8-10 people in the alliance. More would show up as the night progressed (usually when DB's Limbus shell ended its run at 9 EST since he has a lot of Anduril people there). So a pattern developed: start the evening off doing T1s/T2s and move on to T3s when there is enough manpower. Yesterday was the first time Muir and I have ever seen that much overflow. Something like 25 people showed up, and we did our best splitting the ally up to handle two lower tier mobs at a time.
I know it may seem like a waste of time to do T1s and T2s when we have manpower for a T3, but most people look to ZNM night as an opportunity to do the lower tiers because they do not have the time, resources or wherewithal to finish those pops the rest of the week. Anduril events take up 3 days of the week, and some people have other commitments such as Limbus and Dynamis on the Anduril "off-days." You appear to be suggesting doing T3's first and then doing T1s/T2s at the end of the evening, but I'm not sure I understand the point of simply reversing the order in which we kill the mobs. Either way, we will be setting aside alliance time killing lower tier mobs. Reading between the lines of your post, you seem to be suggesting giving priority on T3 pops to the people who HAD their T3 pop before the night began rather than allowing a T3 pop from the people who JUST purchased it that night because we killed their lower tier mobs. THAT is something we have not done before, but if enough people feel that strongly about it, Muir and I can discuss amending the policy.
