Out of curiosity: has there been any information on proposed changes to Viktor that didn't end up getting shipped in his "VGU?"

On the original discussion thread on the League of Legends subreddit, a Riot employee mentioned that they had planned more major changes to Viktor's gameplay in his VGU but didn't end up going with them due to negative feedback from Viktor players.

To be clear: this isn't another "griping about Viktor's rework/gameplay/appearance" or "complaining that he is weak/strong" or whatever, I'm genuinely just kind of curious about what they initially had in mind that didn't end up getting shipped out. Was there any mention of it anywhere by anyone?
