Just Starting WoW

[MetallicaRulez0]

While leveling up, unless you plan on playing with friends all the time, you should go Shadow. It gives you less downtime (Drinking for mana, basically), and gives you a LOT more DPS. You can respec your character anytime you want for a fairly minimal fee (1g to start, going up to 5, and then going up 5g more per respec to a maximum of 50g).

As for sites to visit... I'd recommend the following:
WoWhead.com - This is your database site. it will list where quest objectives are, what items monsters drop, let you fiddle with gear and talent calculators. Pretty much everything you need to know is here.
WoW.com - This is a blog-esque site with lots of itneresting guides and posts regarding different subjects in the game.
ElitistJerks.com - This is the advanced section for everything in the game. For beginners, this site may make your head hurt, but you will learn a lot.

I've just played it for three hours.
It's not super ugly with everything on maximum, so I can live with that.
So far it's only been running from A to B and "kill X amount of wildlife Y for stationary cockhead Z" to quote Yathzee.

I guess if you're a social person you can play this forever (and get seriously, clinically addicted to a point where you only play WoW 23 hours a day).
But I'm a loner, and I don't think I'm going to end up in a guild/clan or something.
Right now it looks like I'll stop before my ten trial days run out.

Yeah, most likely the game that'll ruin MY tiny social life forgood will be Diablo 3 (drooooool!)... ;-)

But like I expected, it IS a huge and well balanced game. Just not 100% my type of RPG.

I notice everyone is missing the all time biggie... worldofwarcraft.com *Gasp*! Yes, it's true, worldofwarcraft.com does have soem good information on its game. For instance, you can go to the class forums and read about the different classes, and advice from other players about how to play that class.
But as to which class you should play, try each out and play what you like. And as for your priest, if you want to make a holy/disc, I suggest you have a friend level with you, preferably a protection warrior or Paladin (tanks) so you can get into a lot of groups for instances when leveling up. Of course, that's a lot more work

Try to get some advice on the pally boards. No, I'm serious. They're almost as bad as the shaman and mage forums.

Quit now and go and reserve Aion. It's going to hopefully put WoW players out of their misery (spelling >.<).
