When looking at open parties they often go without description. When opening one it would be nice if people could briefly mention what they want from their game. Something like "Low-Mid MM, SD/RD", "High Level", "All welcome, AP" etc.?
Sometimes I see a group open and being less than EPIX I sometimes decide to solo queue instead so I don't make too much of a chump of myself with people I don't want to ruin things for. If I know you don't mind low level dudes in there I feel more comfortable that my noobness won't be unwelcome.
