I think the biggest usage will be downloading the game and the patches, I don't think the game itself uses much.
How often do you have to do the patches, I've had the game for about 4 days and already downloaded 2 lots of about 30mbs worth each.
Getting so sick of retards who pick heroes which are obviously not suited to the team. Our team already had 3 casters, the last guy to lock in picks...Fiddlesticks. zzz
Played my first game. I think I got massivley owned. I kept chasing guys and getting killed by the towers.
