Co'hen MacBainBurstar Hmm, consider this.
I've seen a couple of suggested builds like this recently, which go for all resistance augmented shield boosters, and no heavy duty. The other one which comes to mind was the fully-engineered Krait MkII at https://sites.google.com/view/ed-pve-combat/builds/recommended-progression (posted by Episparh a while back).
I'm starting to wonder if I'm misreading the stats on EDSY or Coriolis, because whenever I see a build like that, based on my own experience tinkering with builds I swap out one Resistance booster for a Heavy Duty, and all the stats improve (apart from mass). When I say "all the stats" I mean the effective shield strength rather than the actual resist %, because I assume those are the numbers we should care about?
Usually, if I disagree with more experienced players, it means I'm wrong Am I missing some other downside of Heavy Duty, or just plain misreading the numbers? Or is the extra 10T mass a much bigger deal than I think it should be?
I find that once shield resistances get to about 50-55%, Heavy Duty is universally better.
