It's kind of a strange situation they have. They rain down free lapis and summon tickets constantly, but the rates for summoning non-shit units is so terrible it doesn't even matter. The latest event isn't so bad at least, compared to the last few. You basically have to dump 900 lapis into the premium recipe package, since anyone who tries to craft the ~100,000 cakes needed for the good stuff by using the free recipe is insane. It's not a bad deal though, because using the premium recipe, you can get every single good item and a bunch of leftover from this event by only running 2-4 explorations per day, and that includes 10 summoning tickets (a 5,000 lapis value), so it's win-win all around.
I got my first TM reward (Gungir spear) from overnight macroing recently, and soon I'll have doublehand, ultima, and barrage as well. I also started work on rising sun and kaiser knuckles, but those will take a while to finish unless trust moogles start to become more common.
I'm still salty about missing the mark on all the top tier units, but it seems each time I blow through my tickets and lapis, within a week or two I have it all back again from the shower of free gifts, so I feel less bad. Until I'm cockblocked on content tuned only for meta units, I'll keep playing and doing a few summons a week with the free gifts. One day I'll jackpot and get an actual top tier hero...
Terra and Kefka got 6* upgrades in japan recently, so at least someday in the distant future, I'll have a full 6* team of mages.
