In theory, this could be the case. But for that, nextcolony would have to implement a new battle mechanism. As I analyzed in my last post (and that one is even written in English), the grouping of the ships leads to almost no partial losses. Specifically, all the shields and all the armor of your 12.5 destroyers have to be down before the first one gets killed.
I ran the battle simulator on that szenario. 13 destroyers win against 1 dreadnaught without one single loss. Try it yourself.
I read and upvoted your important comment..
You got some very good points and I believe the NC team is carefully reading and evaluating....
.. lets just assume they implement some changes quicker than the DW team that needed 3 month.. ;-)
