"'The Subtlety Marksman does not have Concentration its tree and depending on how the MM reaches beyond level 11 being full on it's talent tree, the MM can only rely on up to 30% of critical strike unless the tree build has been crossed over in favor of concentration.'"

Oops, the reason it say that the SMM has concentration on it's tree is because it used to, but it got updated since and I've forgotten to update this page when updating the Marksman page.

"'Further, Quick Aim will quickly reduce Concentratioin because Concentration is applied per shot. Which means that if the SMM is not skilled enough to designate an attack to a heroic or boss target, the SMM could lose a well Concentrated shot to a Ghoul.'"

I'm not too much of an expert of targeting priority but I'm pretty sure most bosses would have a higher priority than a Ghoul. So while it's still certainly possible, it's not like you are going to waste all of your concentration on Ghouls, assuming the boss is visible and in range to you. And yes, I am aware of how concentration is applied per shot, that's just the downside to pairing quick aim with concentration. The Barrett is a slow-firing, powerful weapon so it's better to use with quick aim and concentration than other weapons like a UA GPR-12 for example.
