Talking Point of the Week: Using other people's moves

[Poit]

TLP Talking Point of the Week:

With Seth Rollins apparently using the Pedigree now, we're going to be discussing wrestlers using other wrestlers' moves. Examples include Seth Rollins using the Pedigree and the Miz using the Figure Four, both with the blessing of their previous users. There are also cases where moves are copied as a parody, like when Mickie James started using Trish Stratus's Chick Kick. Ans of course there are Rock & Austin, who would sometimes use each other's finishers on each other.

What are you thoughts? Do you like or dislike when wrestlers use other wrestlers' moves? Is it appropriate for wrestlers to add other wrestlers' moves to their permanent moveset? What about just occasionally using someone's move against him? Why?
