Here's a list of (hopefully likely) unintended interactions for Yamato ultimate
Anything % based in interaction, e.g. Kelvin slow from arctic beam or Geist life swap, goes through in full on Yamato and is not reduced in CC effect or effective damage. For CC effects, like Kelvin slow, they do not recover any faster
If this is intended, then Grey Talon's ultimate is bugged and cannot execute Yamato when below the 22% health threshold
Silencer (6500 cost weapon) silence is the full 3 seconds, not reduced by 80% debuff reduction
Sidenote, Melee Charge the item delays light attacks from being instant hitboxes to being slightly delayed. During Yamato's ultimate, when she light attack spams, the reduction without Melee Charge allows her to get every other hit in. With Melee Charge, the opposing character can parry every light attack. Testing was done by having a heavy melee attack be parried during Yamato's Shadow Form and then pressing light attacks as quickly as possible.
