KibblesTasty is a super talented game designer whose clever insights and community are among the ones I admire the most. His famous Inventor class is what I'd play if asked to play an Artificer. If you've playtested any of the subclasses from the Saddlebag on Discord, you're familiar with the series of feedback questions I ask: those are based on questions Kibbles asks his patrons, and they do a great job of developing the content further.
KibblesTasty isn't afraid of making full on classes for 5e. He's also been working on a Summoner class I think is especially clever. The above images are for his in-progress martial class that doesn't take the Attack action often, unlike the Fighter, to instead offer unique opportunities or effects that influence the battlefield. The images above offer a look at the base class and two subclasses, but the PDF below gives a ton more (19 pages, instead of the 5 shown above).
