quick fighter question

[Chainsaw]

is the attack triggered when a marked opponent shifts (instead of attackign the marker) an opportunity attack that benefits from the combat superiority bonus?

No, it's not an opportunity attack so it doesn't gain combat superiority or any other bonus to opportunity attacks

Makes sense. We have been playing it as you described, but I had a momentary panic attack as I was looking through my PHB.. thanks!
