To be clear, ideally the primary stat system would work out in which:

With decent gear and stat allocation while leveling, most players could assume that they would be capable of hitting the "hard cap" on a single stat for Intelligence, Strength, or Finesse.

This then leaves the player to choose between:

"Do I want more Constitution to live longer?"
"Do I want more Wits to crit more or have better Initiative?"
"Do I want more Memory to have access to more Abilities?"
"Do I want to Hybridize into another Primary Stat?"

Ideally, this should give Hybrid characters room to exist, at the expense of one of the other three areas.

This is where my adjustments to Memory would allow a Hybrid to function very well without any or few Memory investments, where as a Generalist would likely need to invest more in Memory to really have access to all of the abilities they want, while a Specialist will likely want to invest in simply more health, crit/initiative, or yet more Memory to maybe include multiple Master level skills.
