It just doesn't feel like a tradition. It feels like a talent. And you're missing the point with the penalized area. the idea is that the practicioner would never even come in contact with the penalized skill. A Dabbler doesn't even get access to necromancy, so it's a plus flip to sorcery and no downside. I'm sorry our discussion doesn't make much sense to you. Let me explain:
Dabbler begins with a Sorcery Magia and a Prestidigitation Magia.
Graverobber begins with an Enchanting Magia and a Necromancy Magia.
Tinkerer begins with an Enchanting Magia and a Sorcery Magia
Options for tradition magic:
Sorcery and Necromancy
Counter-spelling and Harness Soulstone
Enchanting and Prestiditigation
Counterspelling and Harness soulstone is a really good pick, I think. i like this option for tradition magic. I'd actually like to take this as a guard or scrapper character and make a "Mage Hunter" type that eschews all types of magic, including the malifaux soulstones.
the other two, though, have no downside for any magical pursuit. It's a boring plus flip to a skill, completely unsupported by the fluff. It's a safe choice, which is fine, but I think we're looking for something that would be more of an overarching "Theory" instead of a talent that we can get for free at the beginning of the game.
