It's stupid how you lose multiplier in spectator now. Even if you didn't spawn and click on a team, and they happen to lose, you lose your multiplier. If a map ends and you have a x5 (or any other multiplier), and you don't even spawn the next map, being in spectator will make you lose your multiplier as well.
It's like "KEEP PLAYING UNTIL YOU LOSE YOUR MULTIPLIER OR YOU'LL WASTE IT BECAUSE IT WILL GO AWAY ON ITS OWN."
