The teachers here in Toribash are normally decently high skilled, but it appears as though the majority of them are inactive.

In particular, I noticed that some teachers are great players overall, but have a low ability to explain how a player can refine his or her skills.

lastgod: exactly!!!!! thats why i notice some teachers are not helping that much becuase their either inactive or lacking the ability to explain to students on how to improve their skills
