The Forge Adept is decidedly worse than the Battle Smith, Artillerist, or the Armorer in combat and honestly, I would still take the Alchemist or Cartographer due to their utility. The Mavrick is even worse it focuses on improving your spell list but until 15th level you don't really get anything.I mean, they're probably not as good as Battlemaster or Artilerist, but I'd definitely put them above Cartographer!
In that book their is however a great monk subclass focusing on enhancing shifter, warforged, changling or kalashtar albitites in melee combat.
In Dread Metrol you have a class that is very similar to the Armorer but no ability to choose between forms. You replace parts of you with artificed versions, gaining the ability to use heavy armor as well as a 1d10 int keyed enhanced arm. Two attacks at level 5, then an extra infusion slot at 9th along with your arm counting as a shield and your weapon bumping up to 2d10
Your weapons however deal a good deal more damage at 9th level. Finally you become a construct at 15th. great class.
