I've played Dota 2 a few times. I am terrible at it. I have no idea what's going on. I'm also not sure whether my computer can handle streaming it. But we will find out today!
...Or maybe not! I waited 18 minutes for a "passive bots" queue, gave up, tried an "easy bots" queue for 8 minutes, gave up, and played LoL. Someone picked Vayne, I picked Udyr and said I would top, then the match starts and Vayne goes top. So I had the privilege of going Udyr/Poppy vs Sivir/Nami. And our Poppy's computer was "lagging" and "freezing" a lot, apparently. We died a bunch. It was bad.
