It's very ignorant of you to make that comment about high levels never helping. Perhaps they can tell how rude and arrogant you are and avoid you on purpose. ^^ And if you no longer think this game is fun, you might as well stop playing since you have genkai to look forward to every 5 levels after 50 anyway.
My experience so far: Linkshellers went to the Nest on two occasions to get Exoray Molds. Both times we had 10-11 people. One was a Ninja 58, and the rest were 50 or below. We got 9 or 10 Molds (I forget how many we needed) in four hours, tops. (I wasn't really paying attention to time.) We had one TH2 and no downtime other than waiting for Exorays to spawn. Now on to the Explosures and Liches... >.<
