If you could see one character from classic return

[Andy]

She became Sheriff but it was destroying her so Dave stepped up to take the pressure off her

That’s if I recall some fiction correctly

[Harlath]

So then the rather large question is why isn't Wendy Sheriff at the start of Reloaded?

I can't remember the specifics (or more helpfully, the "why?"), but this was part of the FAQ that AEG had when the relaunch was announced and not having Wendy as Sheriff was a deliberate story decision.

Thinking about the why of it all is that whoever was Sheriff was doomed from the beginning and they would much rather kill Dave than Wendy
