The change has made it even harder to breach PD, even if the player is inactive. Before I could send 150-200 destroyers and most likely what arrived at the planet would capture it, now the percentage chance is so low I need to send massive fleets. The good side it is possible to destroy a players PD.
Maybe the change will stop players like Uranus sending tiny fleets all over the map to grab new player planets, maybe not, but wars just got a whole heap messier. I've decided to do some mass arc expanding while simply doing the minimum to hold my borders, from what I've seen now I need fleets in the 400-500 cruiser range to effectively fight guys like Flyingmana, and that is just too much waiting around for resources, think I will expand right up to them and build PD's along their borders. It is also slow going, but more satisfying somehow.
