I make it kind of a point to clear all the event dailies. Generally, that gives me enough currency to clear the event store or the event gacha. I did a full clear on the event gacha now as well, the lower tiers are pretty cheap. Cheap enough that it's doubtful that it'll stop me from doing the higher tiers. There's still a nice amount of gold hidden away at the lower gacha tiers. The 3* girls can be traded for gold (bond crystals are just an extra). The gacha seeds can be traded for equipment, 2* girls and 3* girls, which can again be traded for gold. And I'm always short on gold!

Page 8 of the event gacha also gave a bunch of lvl 100 bloom dragons, which is nice, since I just ran out of several of those. So that's two bloom dragons of each colour less to farm.
