I think Dido got a quite a bit of a nerf with the changes to harbours / lighthouses (lighthouses get the +1 hammer from sea resources harbours used to have, and harbours are now just a buff to the distance of your sea trade routes, which makes them much less useful early). That's quite a lot of extra early production ahead of what anyone else with a similar start could get lost in one fell swoop.
I know the lighthouse is getting more production, but are you sure the harbor is losing its? I think the free harbor could still be strong though. You are getting the free internal trade routes early in the game (the ones you get from roads and all), when gold is rough, and you'll start out with longer naval trade routes. It's like having part of the Arab UA.
