Currently, the only boosting strategy is to fill up the lobby and share kills.
Everyone is assigned a turn. When it's your turn everyone else runs to a dedicated area of the map and you kill until you reach 24 kills (25 ends the match). After that, the next person goes. Alternate through everyone, rinse and repeat.
I'm a level 44 and I calculated that it will take me approximately 50 more matches to reach level 50. Each match is about 10 minutes. This equates to about 8.5 hours.
