[Gameplay]Masteries Player Duplication Bug

Today I found that you can duplicate a players mastery pages by doing the following. 1.) Que a draft pick game 2.) View a players masteries that is on your friend list 3.) Accept a match while still viewing their masteries 4.) When the match loads you will see their masteries in your masteries selection instead of your own

Notes - Haven't tested whether this is purely visual or whether you can get higher level masteries through this exploit
