I'm a 21-year-old Finnish professional DotA 2 player. I've been streaming really actively now for about a month or so. Since Earth spirit was put into the game, I've been pretty much playing that hero. I think it has had a big impact to my viewer count, but I can't see myself getting stuck to that hero forever though. I've had my competitive experience with ex-QPAD (SingSing, Wagamama, Select, Mini) and old Heroes of Newerth in a team called KD. (Era, Rexi, etc.) Since I'm not in a team right now, I'm fully concentrating on just streaming and I think it has become a huge part of me to just stream every time I play.
I would say my activeness in stream depends on how many cups of coffee I have had, but usually I'm very active with the commentating. I have my ingame knowledge that I'm willing to share for everyone. Because I have my positive attitude, I'm a little different than "usual" Finns, but I still have the strong accent in my language. But hopefully it's just a plus for me. I don't really have future plans at the moment, so you can expect quite a lot of streaming.
