Oh, Artificer is quite fun. Makes a good weapon user, makes a good implement user, nice range of interesting effects. The problem is that it doesn't have a lot of options, so every artificer winds up being built the same unless you multi-class.
Later material also make some builds more effective. You could spend a feat to use crossbows as implements, so you could take weapon and implement powers together without having to spend extra cash maintaining an implement and weapon.
Class itself also synergizes (though MC or Hybrid) with Warlock and Swordmage quite well, so there's some flexibility there.
Just that a straight Artificer is pretty bland, with only two choices: Weapon user with the Battlesmith (I think that was the name) PP or an implement user with summons. Dragon was at least decent to them.
It's just the Self-Forged PP that was complete and utter shit.
