Artificer is a highly underrated class that would bring not only a higher level of replay-ability to the game but add many additional elements to current playthroughs. I'd love to see more classes added, as I'm sure others would agree, but I do believe more people should get behind the Artificer as it would truly help open the community to even more amazing gameplay mechanics and ideas which just further enhances the overall Tabletop, pen and paper community as a whole.
