I've been attempting to design a 1.5-2bil supership, or some sort of fleet that doesn't die to unfortunate hits from 50-60mil+ power fleets (playing on PVE server to get my feet wet until dday on normal server), but as of yet I have still consistently lost ships against fleets of 50-60mil+ power.  First error I made, now knowing it, was stacking them all in 1 fleet stack.  But other than that they have a cost of 1.67bil, 77% accuracy, 60% absorb, and 855mil hp (804mil without commander/mothership module bonuses).  If this is even possible, of course.  At any rate, suggestions and reality checks would be great, as would suggestions related to how I might accomplish what I seek to do anyhow.

Setup follows, all components are 8wt except for weapon, which is 2 (don't remember WHY it's 2wt, likely no reason at all) and the powercore.  Yes, I realize that they are not all under 100 credit costs, but some I felt were worth the little extra, since it already cost 1.65bil anyways.  Anyhow, suggestions, criticisms, etc are welcome and appreciated
