Kingslayer/King’s Landing

I'm surprised that WWE is so blatantly using Game of Thrones names for Seth Rollins.  The Kingslayer nickname was probably OK, but Cole called one of his moves last night "The King's Landing," which I hadn't heard before.  Usually when they rip off something from pop culture they alter the names slightly to avoid legal issues and get a new trademark.  Any idea how they are getting away with this or why they would be so obvious about it?

I've never watched Game of Thrones so I wasn't aware that it was a thing they were doing.  I mean, you can pretty much call a wrestling move whatever you want because it's impossible to make a case for confusion in the marketplace with a TV show.  So that's likely how they're getting away with it.
