Well the problem here is you only get the respect of someone by beating them. If you don't play in their circle, you are not going to get the respect (rating) you might deserve.
I know of a few players that can't get into "Friends Only" games but are better than players that play in them frequently. But all it takes is one person to help them get in and then they can usually play ith that group whenever they want.
I can think of a lot more overrated players than I can underrated.
Underrated list.... those players that are in the Top 20-50 players right now playing on the Zone that aren't "as popular": _Tkn_Rage, __Mr__Black, DevilZ_Mantis, SKATTSMAN, AQUAKIKO, SchumacherRocks (smurf but still good), and Espro_yu. When I think of more I will add them.
