I had an interesting idea, something that could have been, but I'm not actually asking for, because it's so crazy.
What if Warshade and Peacebringer had been MODIFIERS to existing Archetypes?
Like, if you roll Peacebringer or Warshade you also pick another class (perhaps out of a limited selection) and choose DPS or Tank.
So, for example:
I choose Warshade, and I choose Corruptor, and I choose DPS.
I get Umbral Blast as a primary and a Corruptor secondary of my choosing.
Another example:
Let's say I choose Peacebringer, and I choose Scrapper, and I choose Tank.
I get a Scrapper attack set of my choosing, and Luminous Aura secondary.
CRAZY, I know.
