A while back I had a post about PVE vs PVP servers and how PVP servers no longer serve their original purpose as the only available PVP a player can have (since now we have battlegrounds and arenas).
Today, Blizzard announced that people from PVE (or "Normal") servers can pay to transfer to PVP (formerly not an option), and my 3 reasons to roll PVP were reduced to 2:
Learn to play your class in high-intensity conditions, thus becoming better at your class faster. I personally think that you can learn to play your class just as well in battlegrounds. Twinks are similar to high levels in that they have an unfair advantage and you have to figure out how to withstand them, and you can forge your skills on a fairly even field of battle.
Get bragging rights with all the schmoes who actually care whether or not you had to withstand massive gankings like they did. These guys are the ones who make fun of you for pretty much any reason they can yank out of their pasty white rears. They'll be the ones going "HAHA, you don't have the max gold limit and I do, HAHA!" They have no life and their opinions don't matter. Don't waste your time trying to impress them, because you will ALWAYS fail, even if you accomplish everything in the game they have and even some they haven't. They will never ever respect anyone other than themselves.
So, yeah, if you have the $25 per character to level PVE and then transfer, I say go for it. Take it easymode, because the only people who will grief you for it are the ones nobody likes anyway.
