How important is a synchronized first gear? I mean first gear is generally only a take off from a stop gear.

Yes.
I have a A230 gearbox and at slow speed, I often use the first gear as I would use the second gear with a 4-speed gearbox.
I don't know if I'm very clear, but the 1st gear is fortunately synchronized :)
