Find people to get you on youtube, Play well in Matchmaking, try and get relationships with known / good players. If you have access to play on someones live stream, take it. Be active on forums, help people out, and generally be a nice guy (But, it doesnt mean anything if its not sincere!). Get on a good GB team, Make a montage, and theres plenty of other ways to get known. Just do what you can and be dedicated and respectful, you'll get there.
