This is the blue post about the 7.1.5 changes on MM hunter
Marksmanship Hunter:
We agree with players that Marksmanship currently relies far too much on Patient Sniper not only to do good damage, but also to make the rotation feel fun and rewarding. As such, we’re changing baseline Vulnerability to essentially bake in Patient Sniper, and adding a new Patient Sniper talent in its place. We are also adjusting some talents to allow for more diversity within talent rows and reflect the change to the base rotation. In particular, the Level 100 row: while Sidewinders was commonly used in all situations for its effects on the rotation, we’d rather the base rotation felt fluid on its own, and Sidewinders was a talent focused on the wide-area cleave that is its most clear purpose. Among other changes to help with this, Marked Shot no longer requires the targets to have Vulnerable to do strong damage, so builds without Sidewinders will be able to use it more effectively.
I dont understand this part

What they mean? They will buff the base damage of the Marked Shot?
