So, I'm starting to enjoy SC2 more and more for each day that passes (especially watching the high rated players). So I thought I'd share some great casters for you all to enjoy, check out these youtube channels:

If you are interested in learning how to play Starcraft II at all THIS IS THE GUY TO WATCH! Pretty much all of his videos are chock full of information you NEED to become a great Starcraft II player. Seriously, if you want to improve, you wont regret checking this guys channel out.


So, anyone got any comments on the channels I posted (or maybe you have some favourite casters of your own?)
