Heaven forbid the game not be a level grind like every other MMORPG out there. Even after you hit the level cap, you still continue to get skills and you can even change your secondary class later in the game from what I hear.
That being said, this game is extremely fun and I do highly recommend it. Especially if you have a group of friends to play with often. I try not to group with random people as they tend to be pretty stupid some times. I am currently a warrior/ranger at level 14 and the cooperative missions and quests just keep getting better and better. Now that I am further into the game, real items are starting to drop as well.
If you want to look me up, my in game name is Riv Iqueo.
If you love Diablo 2, it will be almost impossible not to like this game. There are numerous similarities and great improvements over Diablo.
Oh yeah, this was me yesterday:
