I just finished a 4th weapon at 159 FATEs; that's 42 medals for 159 FATEs, or 1 medal per 3.8 FATEs. (about a 25% drop rate)

Extrapolated, it's a rate that means about 844 FATEs to finish all the weapons.

You start the event with 1 yo-kai medal, which means you can start the entire process grinding for both legendary and normal medals simultaneously.

The drop rate is far from "worse than Atma"; however, it is still a tedious process as some maps have horrendous FATE spawn rates and/or horrendous layout that makes trekking to FATEs a massive pain. In the end, it's very tedious.
I'm 22 medals and 1 legendary right now. RNG sucks.
