You say that as though you need to be tougher or somehow better to "handle pvp". I'm up to about lvl 55 at this point and I get ganked a LOT. And every time I see my killer, their level is ALWAYS "??". No one ever attacks me unless they know the outcome is a foregone conclusion. So you're telling me that you're so good and so tough that if someone that far above you attacks you, you can "handle it"?
I honestly don't see the point to a pvp server. What does a pvp server give you over a pve server aside from the ability to attack people that don't want to pvp? WoW is about choice. Horde or alliance. Warrior or mage. Mining or herbalism. Raiding or solo play. So what's the point of forcing pvp on people? It's not like you can't pvp on a pve server. There are still battlegrounds, dueling, arenas, and you can simply mark yourself for pvp. From my perspective, the only thing a pvp server enables is ganking.
And before you tell me to go look for a pvp server, show me one. Five years ago, the landscape was filthy with high-population servers. Today, it seems that icecrown is the only high-pop high exp lvl server in existence. If there were a busy pve server out there, trust me... I'd be gone.
