Can fiesta loadouts get some ?combo bias?

No 2 weapons of the same type/ use.

Hammer sword
Sniper/ stalker/ shock riffle/ skewer
Commando Br
Side kick/ disruptor

Make an algorithm that generates all combinations that aren’t of similar weapons.
an generate a list of 30-50 possibilities without matching class.

I could get on board with that. Or at least ensure your primary and secondary are from two separate weapon tier groups.
