Spawn Gate
On Summoner's Rift there is that good ol' 15 second timer before you can leave the base, giving people time to buy items. formulate a plan, etc, and most importantly balancing the start of the game. This is not the case on both, the Twisted Treeline, and the Howling Abyss maps.
I have been playing since the beginning and am all for the good changes. All I am asking is that you just simply add the Spawn gate to the rest of the maps. :D
