I'm a bit biased towards accepting Staff members but besides that, I don't care about what rank you are as long as it's one of the three. There is no specific rank distribution.
Perfect. Thanks for confirming what 1miau assumed, stating the only important factor is the quality rather than the rank. It was just likely to other users since in most sig-campaigns the places will usually be replaced with same ranked members - good to know you have a different approach. Be prepared for the next run towards the open seats (if any will be re-filled)
