New 5v5 Death-match Mode for Summoners Rift

I was sitting around playing league last night, and I was getting tired even after 35min, so I thought to myself, how can I make a gamemode that lasts 10-15 minutes and is based off of kills, not objectives? Well after sleeping on it, and some inputs from friends, I have found a way, it'll be a Death-Match style of game. Timed at either 10 or 15 min, to keep games short, all Summoners will have access to unlimited gold, as well as all Champions will be level 18 at start. Yes I know, sounds crazy, but there will be no turrets in the lanes, no inhibitors, and no nexus, as well as no camps and no Baron. The gamemode will be a full brawl. Once champions leave spawn they will not be able to return, like ARAM, but with a twist, no spawn pool turret, once out of the protective circle of spawn, you are to stay alive by any means possible, aka kill everything on the enemy team. Once killed your champion will respawn and you can go out and kill some more. I feel this gamemode will help teams train for large team fights, because with so much damage going down, Summoners will have to communicate to each other just to stay alive. However this gamemode will make scaling champions (Viegar, Nasus, Sion, and Thresh) less of a burden to deal with.

Please leave feedback on this idea, both good and bad, if you have any ideas or concerns please comment below.
