I think the most disgusting thing that can happen to characters happened to Suguha and Sinon. The author of a work should never listen to strangers. He almost certainly had a full-fledged branch for Suguha. But he destroyed it, even though he asked the subscribers for their opinions, and now he doesn't really know what to do. Yes, it's relatively clear with Suguha, you need to weave the love line of a brother and sister. But it all looks like it was invented along the way. While Liz has a branch in the game written from the very beginning and it is clear to the author himself how to develop it.I kind of think Liz gets too much attention, to be honest. She was introduced in Part Two and now has way more and better CGs than Suguha, who was originally the second FMC of the game. This is really disappointing because Liz is a far less interesting character. I hope the next update gives us either a really big event for Suguha or Sinon...
On the other hand, for the remaining 6 updates, it is quite possible to make Suguha a favorite of Kirito's girls.
