I'm not a big fan of 4e and it's take on classes because it "streamlined" them somehow; however I did play an Artificer back in the days of 3.5e - and also I'm a huge Eberron fan.
That said, I think Artificer is akin to the Bard: he's a jack of all trades with sauce. Bard's sauce is music. Artificer's sauce is items... and that shows the only problem with this sub-class design: there's a point where a concept deviate from "basic" abilities that makes it hard to fit in that class. That's the problem with Artificer:
*He's a spellcaster... yes. But shouldn't be able to cast as well as a wizard - the class used to emulate part of this through magic items.
*He's a skill/tool monger... yes. But less than, say, the Rogue or Bard.
*He had a "familiar" in the form of a homunculus... yes. But it was also another magic item, and could be tailored to be more akin to Ranger Animal Companion
*He's a capable combatant... kind of. Could be a second liner if build in that way.
*He was a great 5th-party-member that could fill in the gaps
So... I don't thin he'd be a good subclass for wizard, not only because of hp/proficiencies/spells/skills lists and options but also because the class is supposed to have another role in the party and a strong "item" flavor.
