Yeah, I'm actually really grateful that this is a RB event.
Using the current stamina cost drop I'm catching up with various missions, including story missions (and national missions without the drop) mainly to gather some FGs for the next 2017 gacha roll.
It's not really a rest for me, since I'm burning stamina potions like crazy, but I got 2 rainbows out of it so far, so I'll keep going as far as I can.
