A way to make the games end quicker....
I was recently playing with the settings for 2v2 game.
I put on High damage for creeps and low whatever for towers. I was plesently surprised to take a down a tower in the first 2 minutes of the game play. Every successive time I took out an opposing demigod I would run to a tower and raise it. I also took a side portal and watched as my creeps picked apart part of the nightmares base for me. If these settings were the new "Normal" settings I think it would make the gameplay more pleasing. The game I played lasted around 15-20 minutes.
Try it out and let me know what you all think.
