I still think your solution to getting rolled by 'leet' V14's is poorly thought out. The champion point system makes the segregation-by-level system ineffective. I have a v1 toon with 150-some odd CP and is decked out with blue quality crafted and looted set pieces. I sincerely doubt that a player's first V10 toon with only 50 CP will have much fun against a group of players with toons like mine.
On top of that, this system wouldn't work because the campaign would be severely underpopulated. Players want to group up with their friends. If a player is making his/her way through the vet levels for the first time, they may want to group up with friends/acquaintances of a higher level. Another player may be having fun on an alt while running around with friends. From what I've seen, Blackwater typically has a lower population than any of the other campaigns. Yet, if you sit around in zone chat on any other campaign for an hour, you're bound to see level 30's complaining that they're getting wrecked while spamming LFG and wondering why nobody wants to group with them. This idea would only work if V1-V10 toons were only allowed to play on this campaign.
On top of it all, PvP becomes less and less populated by the day. Adding yet another campaign would only make for new buff servers.
Seeing that several of your posts have been subject to moderation, it's clear that there are no ideas left to support your idea. Thanks for contributing to the forum community, but I don't think most players would agree with this solution.
If you want to fight everyone on an equal footing, a progression MMO is the wrong spot. Leveling- and gearing-up are a core part of the game. The imbalances you don't like are the reward for progressing.
Moreover, further segregation of the player base will make Cyrodiil seem even less active than now.
