If you're trying to hint that req hops for our "benefit" think again. It's extremely difficult to move a large group of players, and each time we moved has been in an attempt to balance rvr and stimulate pvp.
At the end of it all I've pretty much concluded that one side will always be stronger then the other. Some people give up easier then others, and ultimately the best way to remove the tug of war and make things more interesting in RVR would be more factions, and remove gp loss from deaths, maybe.
It is almost impossible to have a balanced tug of war, it has happened a couple times.. very rare. Some times it has happened and it just ends up in a lag fest anyways.
And to make it harder for people to simply join the stronger faction. If there are people who leave for their benefit, it would be the ones who simply bandwagon over.
