seriously dragoon is too OP. It could be done so it could have 3 or 4 additional traits. You could still have multiple aspects by implementing the dragoon trait multiple times, but it would take a lot more effort. in exchange for that, you could allow aspects with double stats or triple damage to stack
Yeah they are indeed too OP, but I'm thinking about making them not being able to get the same aspect twice, so that you can't infinitely stack damaging aspects like vampiric and can only fracture one trait.
If that's still too OP I'll probably make it a fixed number of aspects; the main problem with that is to figure out what's the rule of replacing old aspects.
