Valkyries ULT cancelled? LOL

One bullet and Valkyries ULT is cancelled. RIDICULOUS! You are supposed to be able to escape! That should be a part of the game design. Thats the idea!

Its an ULT and it gets cancelled when Valk is shot at?! It doesn't make sense! Its enough that its delayed at start and you take damage. Cancelled as well? One of those perfectly annoying game decisions that doesn't make sense. Does the ULT for any other legends, like Wattson get destroyed in one shot? No. Explain the decision and reason for why Valkyries ULT is cancelled by one bullet, I'm curious. Re-design it.
