Well, no one can deny the vid of the ranger jumping 10 meters at a time...that's not latency that's a blatant cheat. Latency problems are more like small teleports where movement is not static and also where the player might be rubber banding.
Any decent player can tell the difference, so stating the obvious for those that know only makes others think your taking their side.
In my experience, most cheaters hang around together and know each other. People just do not do it independently, so my advice for everyone would be wait for the merge and lets see. In 1 week after the merge any vet will identify the cheaters and which guild(s) harbors them...
