You could combine PVE servers to make more full versions.
When I was last on BC, 7 out of 10 channels was high, the other 3 medium, just a packed house.
But a new PvP server would get instantly packed as people want to be at teh top of the ganking pole since there is so little infamy penalty.
5, but you don't have to grind dungeons. We have a large open world filled with people to play with. This isn't a lobby game.
Wow this got off topic fast. The point was, ALL PvP servers are 100% full with queue times. NO PvE servers are full, or even remotely near full. So just transfers all the peeps off 1-2 pve servers to another pve server, and make those servers pvp. I didn't say anything about making PvE carebears forced to fight anyone.
Watch the population plummet on the pvp servers once people there have to pay. I would wager a guess that most of the people on those servers are using buddy keys or 5 dollar pre order with no intention of buying the game. This is just my opinion and observation from other games that have done something similar.
