There is a reason there is best of 3, to eliminate the chance of an undeserved win.
Also forget about the "lore/reality aspect" of, your mech just blew up, how can you fight again?....well guess what...thats what QP is isn't it, you die and immediately drop again? You don't have to repair your mech or wait for a mechanic to fix it, so don't use it as an excuse not to implement best of 3 in Solaris.
Its a videogame.
EDIT:
This will help your player retention in the mode as you dont' have to keep dropping back to the main screen to get back into a match.
It'll also let users actually view a match from time to time.
