I don't think I get mad with SPers, even if they're learning. I'd have to ask @Chew; if I was ever rude/angered when playing with him. But I like to think that I'm nice and friendly. Bot matches helped a lot when answering some of Chew's questions because there's no pressure anywhere and it's much more "relaxed". Feel free to contact me if you change your mind.
And yeah, 500 is a lot but it's been like 8 months or something like that and I don't have any other hobby. I just study and play/watch Dota, kinda.
