Sorry if all sorts of people come in and post this same topic, read a few pages of the forums and didn't see much, feel free to send me off to some other topic though if its been said

Right now I'm a WoW player and while I enjoy the PvE of the game where i truly have fun in online games is the human competition (probably why i still revert to WC3 and UT quite often) and as you may or may not know in WoW it can take quite a bit of time, despite being better than some other games, to get up to snuff and have some real level 60 PvP fun.
I have been looking at GW because it reminds me of one of my favorite old MUDs where there was much less grinding than many others and the PvP victors would be based largely on the skill of the player, rather than the amount of time spent grinding somewhere. I know GW obviously has some grinding, it is just a part of the genre but my question is whether one can have fun in the PvP game of GW without 200 hours of bunny rabbit slaying.
If I purchased the game I would certainly start out with the PvE to get the gist of it but would then probably want to switch to mostly PvP, are the non GvG arenas layed out in some way that newer, weaker players are in certain arenas and the better vets are in others, or do you esentially get your head handed to you on a plate 300 times before returning to PvP for another 50 hours of skill-finding? Also, is it reasonable to find guilds that are more casual? (I would assume given the # it must't be to bad?).
Thanks a lot,
