Repairs, mines, and more

[CrazyJoker]

I haven't noticed any of these topics covered previously but I figured they're all small enough to cram into one post.

My first concern is about repair bays. In BF1942 the devs set-up repair bays that were right next to if not in the middle of important bases. The smartest and cheapest tank drivers eventually figured out that you could camp on the repair areas and your chances of getting killed were very very low. I'm wondering if the devs have mentioned how repair bases will be set-up.

If an engineer is repairing something can they remain cloaked or is it similar to firing a gun; Once you're doing any sort of action other than walking you lose your cloaked status?

Lastly I was wondering, if you have whatever cert allows for minelaying can you also be a minesweeper? I haven't read anything about being able to deactivate opposing empires' mines but I'm sure there is some sort of system set-up to do so.

Except the first one these aren't major concerns just simple curiosity on my part.
