Who should say Hong Kong Attitude?
It is not the casters' responsibility to say Hong Kong Attitude, it is the fans' responsibility to let the World hear it. Do not chant HKA! HKA! HKA! in the World event. Chant Hong Kong Attitude! Hong Kong Attitude! Hong Kong Attitude! There is nothing wrong with chanting for a team using their full name. Let the venue echo it. Let the World echo it! Now, if Riot will broadcast that chant, that is a different issue.
