Subclasses seem to be more of specialized class (hence sub-class) that takes a base character class in a different direction.
Of the two, subclasses seem to have more power/abilities assigned to them than a feat path would. Subclasses "lock you in", and a blood magic subclass for a wizard would have to be rebuilt for a cleric. (I did this with rune magic, made two separate but similar subclasses).
But what about a standard wizard, say an enchanter, who wanted to learn blood magic, they cant multiclass into it, but you would think they could learn it? So feat path.
So I am leaning towards "styles" and "traditions" being feat paths.
But I am curious about the power levels. Obviously if you have a subclass and add a feat path, you have more power. But anybody can take say any three feats they want as they level, so thats moot. So if my feat paths for elementalists, stay in line with the power of standard feats, beginner, 4th, epic boon etc, then I should be okay.
My big question to y'all is: At what point would a feat path concept be so powerful that you would have built a subclass instead? Or are they equivalent, and should be based on wether I want then limited to a certain class (subclass) or allow anyone to commit or dabble (feat path)?
