Why not do 3 deaths and you're out AND 30 min on timer... If timer runs out whoever has most players still in the game wins the game... Or whoever flags up first in those 30 mins... whichever happens...
Games would be 30 mins MAX... or they can be 4 mins if a team just flags... OR they will be 10...
Nerds camp enough in USL as it is, if it comes down to kills ppl will camp more
