I don't understand how you think that Ren is a master melee fighter. During his fight with the King Tajisu he was obviously trying to avoid a close quarter combat and just shoot it down with his guns. It was only when he has no choice that he took the risk and went in close for the kill.

Yang is the best close quarter melee combat fighter in town, not to mention that the technique Ren used to kill the Taijitu obviously cannot be used on humans. It would kill them.
