How Do I Restore the Old Improvement Rate?

You've always had the option to change the game speed. It accomplishes the same thing you are talking about.

Actually, I've always played on epic/Marathon, it didn't accomplish what I wanted, does now though

I love the changes, it is the first time I reach turn 500 without even near the end of the tech tree, is good, because if you play on the slower speed, you have about 1200 turns, so that means the game has been balanced a lot, and should stay there.
About the workers: I've yet to see a worker "flee" from combat if has hardy, since the nerf, all my workers are killed and none of them flee, even agains warriors.
