What a great game. To get maximum enjoyment, have a friend join and play along. My brother and I use Skype to talk while we play.
Also, know that you can find a trainer to give you new abilities on every EVEN level. (Level 2, 4, 6...) Make sure you get them! There are a lot of beginner guides on the bigger gaming sites like Gamespot.com. Make sure you check those out. They'll give you the basics of the game, as there isn't much of a beginner tutorial. For the longest time I was wondering when my priest was going to learn to wear heavy armor like a DnD Cleric.... (They DONT!)
As for the game being boring, the zones for new characters are made to be PAINFULLY easy. There are bigger challenges just a few towns away.
FYI, there are LOTS of ways to play the games.
If you are anti-social, you can play through the missions solo and have a great time.
If you like micro-management you can play the Auction House and buy-low sell-high.
You can spend endless hours crafting stuff and selling it on the AH...
You can group with people and do the missions.
You can duel with people on your own side.
You can attack the enemy players (PVP)
You can play Capture The Flag. (PVP)
You can play Capture Points-style games. (PVP)
You can do high level instances/raids on big tough creatures and dungeons.
And more... You shouldn't get bored if you have a lot of time to pour into the game...
And the things that make this game stand out from Everquest:
No harsh penalties for death. If you die, you can revive at a graveyard and are weakened for a few minutes or run to your corpse and revive for no penalty. You receive a small ding to the endurance on your equipment, but that's it.
If you are in an Inn or major city when you log out, your character will "rest" and receive double experience while in the "rested" state. Makes it easier to catch up with friends if you miss a few days. I like to play a few characters so the others are always resting.
And as far as beginner characters go, the easier (IMO) classes for beginners to play are Warriors, Rogues, Hunters, and Mages. The others aren't much harder, and people will probably disagree with me...
Eep.. I wrote too much.

Give it a try! It's not a twitch-based FPS or fast paced as Diablo, but it every bit as immersive. (If not tenfold) By far the best game I have ever played, and I'm a hard core gamer and loves games of every type.
