The current rating system is one dimensional as I understand it.
Combat Reputation is based purely on the difference between kills made and kills received.

This gives incentive to higher ranked players who want to pad their stats to farm lower ranked players which in turn gives them incentive to complain on the forums.

If the kill count could be weighted by the relative rank of the kill we could separate the true PVP vets from the farmers.

'Passive' rating could be reserved for people with low total fights.
Players with negative kills would have a title like 'Underdog' if they are being killed by people bigger then them or 'Pathetic' if the kills are coming from lower ranks.

People with high kills against much lower relative ranks would be labeled as 'Bully' for everyone to see. The only way for them to remove the label would be to tangle with some higher ranks which would either reduce their nets kills or increase their relative ratio.
Either way, the story would be told.

well there is a problem with this that I see. some people can't see others around their rank. like me for example. I don't have scanners equipped so I see only people lower level than myself (Rank 208), so I'd be labeled a bully because the only people I can see are usually at least 50 levels lower than myself. occasionally I'll see a level 170 but that's it.

I do like the idea, but it needs to include a way to factor in if people have cloak/scanners equipped when they're attacking so that it won't be an unfair labeling.

Yeah I kind of like the idea up until the bully part. Because unless you get a lot of kills on people you have been alerted by legion alert that are way lower rank than you (say a level 200 constantly attacking a level 50), i would not consider me hitting someone lower rank than me that is in my battle tab limits being a bully. Perhaps making a bit more distinctions as to how they got their kills both in being killed and making the kills would improve this. I would have to make one for my legion leader Hawkeblade of Giantkiller for his battle stat rank the way he takes out people of all ranks. But seriously it would be fun to add more distinction to the combat rankings.
