Officially done with the event. Ran PRO the entire time and brought along my Lightning, Hope, Snow, and Fang units along with a friend Lightning for each run (thank you Gaffers!). That left one open slot, and I just threw in some unit from my TM farming squad because... why not.
But I got all of the tickets, all of the SQ, 4 of the attacker materia, Hope's weapon, the 30k moogle, all of the cheap 6* mats, a few of the higher cost 6* mats just to round out the numbers, all of the gigantuars, all of the mats to make Winged Saint (which is in the oven), and all of the tent/scream root/elixir/etc. items (because why not). I still have ~600 gears left with pretty much nothing to spend them on.
So, basically, outside of the 70k moogle I cleared out the store. I must admit... adding in the fact that I now have a cache of ~30 sacred crystals and got enough megacites to get all of my espers into the mid to high 30's (level 2), this has turned out to be a darn fantastic event for me. Applause to Gumi for turning that around.
