RPG mechanics exist to give structure and consistency to the game world, true, but at the end of the day, you’re fighting dragons with algebra and random number generators.
I guess I assumed (though you are correct it isn't explicitly stated) that metavarients 'are' SURGE.So a dwarf with neotany and a couple of metavarient attributes makes a gnome.An elf with meta Agility and a hair quality and nocturnal quality becomes a Noctura.So because the Metavarients use the SURGE qualities, I assumed they were one.
1) A player is suggesting that cyber spurs and bone lacing stack. I'm saying that spurs aren't 'unarmed' but just use the skillset. You're take?
1: Stack? I'd say no. Spurs are generally retractable, so if they're not out then you use your Bone Lacing. Pop out a spur and you're using it instead. Plus if you're awakened you can have a weapon focus spur.
