Honestly, I dont want the next game to focus on Liu Kang's new timeline. I'd like to assume that there is a timeline where Liu is able to get things right and keep things stable.

There are two routes I'd be cool with. First route, go back to the original timeline. Make it so this whole second timeline was an else world scenario, and show us how Armageddon really would have ended if it stuck with Taven being the winner.

Two, a completely new timeline with no reference or connection to the MK9-11 timelines. Maybe this could be Liu Kang's new timeline, but in a time period before or after any of the central conflicts of MK1-11.

What I'm getting at is, I dont want MK to keep relying on the prior games' plot beats for their plot. While it is cool that they keep bringing back old stuff, this also makes them prone to taking what wasn't broken and breaking it, while also failing to deliver on a lot of their setup for what's next.
