For those upset by this, is it really that unreasonable for the tourney organizers to say, "Hey community, for the events where the game may be getting more exposure, can we try to avoid the more revealing costumes, because there's less chance of someone feeling uncomfortable that way?" Does it really bother people that much to maybe think about how others might feel and do something as simple as picking a more modest costume in a tournament to avoid a negative impression? I mean, is that really that unreasonable given the negative perception these costumes give the game (whether justified or not)? Is it really asking that much?
Granted in the US people are more desensitized to violence than sex, and perhaps that seems silly and people need to step back and think about that, but it's a whole other topic. But given that, in the context of a tournament where the gameplay is the focus, is it really that off-putting to concede a bit on the issue?
