while the two defensive retrofits can be nifty, I highly advise against anyone just throwing Long John Silver out there to the wolves
ECM and projectors will shrlop some hits, but defensive tokens by their nature (exhaust, then discard if exhausted) will crumble against multiple attacks.
That, and if Intel Officer picks up favor (and against the big boys with only one brace token...oh boy) the combo's going to be rendered moot pretty quickly
It's still 15 shields you have to go through with that combo before you reach the hull, plus 8 hull to churn through, not counting a nasty repair capability.
I think people talk about ECM + Advanced Projectors because it's the only combo we know we can do with the two slots. I can't wait for "Redundant..." upgrade which seems to automatically regenerate shields. Like you said, ECM is nifty and all but really works well when you expect to take one/two volleys per turn. As soon as you're going for more than that its value really loses out. So I can definitely see the MC80 with Advanced Projectors (ECM is less needed when you have 2 redirects) and that Redundant ... upgrade to automatically regenerate shields. If it's one per turn, it's interesting, if it's 2 per turns it's **** awesome coupled with the Engineering Command.
