I am to the point where I think I have read too much about specs, including the mut. discussion which made my head spin:

I am mostly interested in PvP. Also, I don't have an end-game toon yet (my highest is a 31 Nelf rogue). The way I see it, I have two options.
First, I could power level my 31 rogue to end-game on the PvE server, which I have to assume is easier to level up than a PvP server with gankage. Once I hit 70 I could focus on PvP competition, and most definitely spec mut. The con of this choice is simply that I am finding leveling to be boring, and PvP play INCREDIBLY fun.
Second, I could change my main to a PvP server, level with talents that help PvP the most. This way I could PvP effectively, and level when I get tired of being ganked. This path will take much longer to get to end-game, obviously.
Since I have no knowledge of what end-game play is like, I really am in no place to make this decision without advice... this includes no knowledge of raiding (is it like an Uber-instance?). I seek advice because the time it takes to level to end-game is not insignificant.
I wonder if avid and successful PvP rogues might post how you chose to level? My ultimate goal is to play a very competitive arena rogue.
