What situations are lord Dominic's better than mortal reminder in their current state?

I guess i will use quinn as an example specifically since that's who I've been playing more lately. When it's time for me to build a Last Whisper item I'm never sure which of the two I should buy. LDR just genuinely looks terrible in comparison since it's same stats except it's 40% shred instead of 35%.

Does the extra 5% shred really mean something?
