A change to ARURF
One of the problems of ARURF, is how fast the game can end. Despite the gamemode supposed to be an over the top brawl, you often end up with someone just splitpushing, until the game is over. And, since towers are easier to take down in URF, in a few minutes, someone can just break all the turret in a lane. So, my suggestion is to make it more like Bloodmoon, with the turrets being invulnerable until a certain amount of time has passed. Maybe, outer turrets lose invulnerability at 5 mins, inner at 10, inhibs at 15, and nexus at 20. Something like that.
