Beware: There is an unadvertised penalty to leaving Last Spartan Standing when lives deplete

I left my first match, and despite having double XP active I did. Not receive any XP. So the XP you get for completing a match is not granted. Additionally, and may have to check this tomorrow, the 300 XP usually granted for a first game of the day was skipped over, showing my next reward at 200 XP. Unless there is no longer a 300 XP reward for a first match of the day.
