One idea I've had is to reward more tournament points for killing lots of stuff, regardless of win/loss/margin - so players in a bloody match that ended 310 to 300 would be rewarded more tournament points than players that killed less than 20 each, unlike today's system where MOV ensures those are both 5-5 for tournament points.
You'd theoretically get a tournament point for every X points you killed, plus a few more tournament points if you also won. The specifics would have to be mathed out, but I think you'd have an incentive to play a full match out instead of just sitting in deployment zones - you might as well engage the opponent if killing stuff is always worth more points than doing nothing. It just makes sense to me that an active, bloody, no-holds-barred slugfest of a tie should be better for your tournament score than a passive speed-0 tie. And if two people still want to collude for easy match points, well at least they had to go roll dice at each other to make it happen.
