That's actually not as awful as I feared, depending on what the drop rate for T4 is.
I've been enjoying having no new event this week! Finished up Ch 6 hard mode and been using up some of my cycle keys. I now have every character at least up to crystal level 47. Slow grind getting them up to 50! Doing a little bit of Tidus co-op for tickets since I got the 800k for armor tokens last week.
