Should a purchase?

Hi,
Im a true believer in the CoH world, it still rocks and i even like this game too... more stuff in it though.
Can anyone answer these questions for me to make up my mind:

1. Do you have engineer units, like in CoH, where you can repair vehicles?
2. Towing arti etc do the logistics of moving units around play a role in much of the game play?
3. Can you build defences, sandbags, wire, tank traps when and where you like (is this sp or multip features)?
4. arti, i love the visual effects in CoH and the impact on the environment too, is this in MoW?
5. I played the demo and found the infantry control different to CoH and slightly worst, do infantry automatically find cover, and can you group units and use hotkeys to send orders?

If you can make up my mind with some answers id would be very grateful.

thanking you.
