Fastest 50 Ult with DVA in quick play not sure if you need to pause the timer when searching or not.

That's a fun challenge to do I have done it once just to try and it was pretty fun.

Can be added for other characters as well.

It seems a bit too arbitrary, but also what do you mean by "50 Ult"?

You need to charge 50 Dva bomb (Ultimate) and use it basically.

Remech doesn't count.
