Yeah I really think death match would be a lot of fun. If it isn't ranked it would be a great time to practice up with a new loadout. You're right about tower control, sometimes it's almost necessary to wipe the other team. With Rainmaker my main thing is this.. even if you do kill the whole team.. they'll be back soon. You're usually not gonna kill all 4 with one or two shots so by the time you get the last guy the first one is back and ready to stop the carrier. Then by the time you break the bubble again the whole team is back on you. The best strategy (in my opinion) is to take out one or two players if possible and MOVE AS A UNIT. If you can get your team mates to flank you and get your back you can more or less ink your own path with the Rainmaker and maybe take out a couple opponents as well.
