Anyways, thought I'd throw that out there. It's a bit more scientific than just scanning the names and picking the best one that suits you that day.
Yeah, I'm familiar with the HF ranking system. I highly doubt that the majority of the people here are using it, and are instead opting for the player that most closely represents their most important piece of criteria (ceiling, readiness, etc). There's probably some picking based on whatever suits a person that day, too.
As a disclaimer, I'm not suggesting that using the HF ranking system is right or wrong.
