I don't see how this encourages world pvp to be honest although I appreciate the attempt at new things. If anything, it only encourages full geared guilds to go at it with each other in Hillsbrad until horde and alliance realize they can actually work together to form a monopoly for the 2 guilds like what had happened many times over in vanilla wow with warlord status which was a large contributing factor as to why blizz scrapped that idea in the first place.
Anyone that isn't in said guilds, would never stand a chance, and would thus never participate. Well, considering the mass of people that keep spawning in their bg gy despite being gy camped, I chance my mind, there will likely be plenty of fodder for the big guilds to toy around with, which is not something warmane should encourage anyhow.
However, if this far from polished idea is to go through, it should cause you to die if you mount up/stealth/etc. Although there will be plenty of tele hackers porting underground to nab it also. There's so much wrong that can occur, and all that I've said required no thought at all, just came as I was typing.
So yea, as much as I love pvp in all it's forms, I vote no :(
