@Riot -- VGUs, Mid-Scope Updates, and Unique Strategic Identities

When champions receive mid-scope updates like Rek'Sai, Talon, or Sejuani, they usually come alongside changes to their niche that better cement their unique roles in the game. Talon for example is now the champion you pick when you want a roam-heavy assassin on your team, and Sejuani's distinctiveness as a vanguard comes from her unique synergy with melee champions. But, for champions who are on the VGU list that have already received changes to their niche in the past, what will the direction be for their kits moving forward? Will their reworks focus around the niches they were intended to have as part of their updates, or replace it with entirely new ones?

Case in point, Mordekaiser's a good example of a champion who's in line for a full VGU but already received an entirely new strategic niche as part of his rework (bot lane AP juggernaut). The update wasn't very successful though, not only in terms of balanceability but also resonance (Morde mains weren't happy with it, and it didn't really fit him as a character). Given this unique situation then, will Morde's rework set out to give him an entirely new niche, or will it focus around making him the bot lane AP juggernaut he was intended to be?

I ask not only because I'm interested in Morde, but also other champions I play whose reworks haven't been entirely successful either (Quinn, LeBlanc). In Quinn's case I feel she doesn't really belong to the marksman class and could use a niche that better suits her aside from roaming, and in LB's case, her niche wasn't really well-executed on (deceiver), not to mention it removed her from the assassin space. In both cases though, it seems like their niches simply weren't unique enough, as Quinn's kit makes it so that her niche ends up sharing a lot of similarities with Talon (roaming burst damage-dealer), and Shaco has the ability to deceive just as well if not moreso than LB while also being an assassin.
