Since I have gotten back to playing around on the battlefield I have found how useful email notifications for it could be. 

Notifications for...

When ten hours have completed/reward recieved from the portal, tree, mine, and other places that give reward.

When squad gets full energy and is ready to move.

When squad gets attacked.

When squad gets attacked and is moved.

When squad is done researching mirror world.

Do others think this could be useful? 

Yes please. Do want o.0

I mean some of those things appear in a log... but I 'd love to know when I can move again, or when I won a prize after my 10 hours.
