Tanks stall the game for way too long
Just won a game even though it should have taken 20 minutes instead of 47. We all won our lanes but couldn't ace the other team, due to their tanky team composition. Rammus, Volibear, Maokai, Ashe, and Fizz. Every time we reached their spawn, they would attack us, run back to heal, and continue the onslaught. Nobody could finish off 3 tanks at once, especially when their was an Ashe in their backline.
Maybe we can we make the spawn pool heal for a certain amount of health each second that's not percentage wise?
