personally, Artificer is my soul class. And while I know that they said it will be only PHB classes at release, it would be a shame and a lost opportunity if they don't make a DLC later on that brings the Artificer to the game.
Think of the possibilities! The madness! eldritch cannons, infusions, power armor... sure, it would be difficult to implement it all, but worth it a thousand times!

I have, however, also seen opinions on this forum that argue that the artificer doesn't fit into the world (which I disagree with). So, whats your opinion? Who is hyped for the Artificer?
