The current system doesn't fix anything, because there's so many people with zero interest in World PvP using it, and the only time you 'lose time' is if you get camped which happens really only in current content zones, and a couple of the zones allied races usually go right into when leveling.

The current system, you can't get anyone to help you vs group ganking because no one is there for PvP they're there for the PvE rewards. PvP talents already make killing stuff faster either via extra defensives, or by extra damage. PvP talents alone, make up for the 'lost time' in leveling from world PvP. Which, is a very rare case by the way, regular wpvp that isn't just a numbers gankfest is quite rare. The PvE rewards are just a means to try to get people who don't PvP to turn it on so wpvpers have people to gank.
