Well, as a male I could imagine to have a triple match like female vs female vs male. As the male I would like to wait how the females start. Then I would support one of them.
To have a formal triple match sounds to me a bit of boring. The theoretical situation would be that the two weaker opponent work together and beat the strongest. After this, the second strongest would come out as the winner of the triple match. To me a triple match would only work if there are other emotions in the match than just formal winning. Dont misunderstand me: A triple match can be great, but it depends on the situation.
