So a lot of good discussion has been had about the PD/missile changes, which I am really looking forward to giving a try.
But I'd like to go back and talk a little bit about the ECM changes. Obviously it now allows you to customize your ECM choices, depending on your fleet composition. This is great, and means that there's more room for specialization. But... if the size and cost is fixed, past a certain size of ship, you're always going to put a full suite of jammers on a ship. It only really feels like there will be meaningful choices at smaller sizes of ships. This may be the intended behavior! In which case, fair enough. But, going off of the example ships posted, it ends up looking very similar to the previous system when there isn't any kind of size scaling for ECM.
The removal of ECCM components is extremely welcome.
