The big problem with "having controll in battles" is always an advantages for the attacer, because they will only attac if the defenders are offline and can´t controll their fleet.

Thats a problem in the actual battelsystem too, but not to that big part. And that is why you can´t choose the weapon you want to use on a certain ship any more, like it was in the very old days.

In my oppinion the two central problems of the stne battlesystem are that you need to be fast do to anything at all and that there is no posibility of big fights. It´s allways 1 Fleet vs X Fleets in the calculations at least.

But as i said above this propably wont change soon
