Hmm, while that
may be true (or not), I feel like it's probably too early to make that sort of conclusion.
It's interesting, though; if anything I expected the rest of your post to be about it being harder to back away from the Remnants, rather than the other way around! But ordering an Eliminate on a Radiant is always a gamble; and I personally would not expect a Conquest, of all ships, to do a good job of that - it may not be a slow ship, but compared to a phase skimmer? I doubt an extra 7-8 speed or some such is the difference-maker in this particular fight, especially over a relatively short time span - you might expect this to lead to a little less hull damage taken, but not be qualitative, I don't think.
My guess would be that it's more likely you're seeing the effect of whatever ship AI changes that were made, but it's hard to say, of course. The larger point is that this feels like jumping to conclusions a bit; likely just some older approaches are less effective now, for whatever reason. (And, in particular, Radiants that come out earlier are much tougher to deal with because they have more support around them!)
Edit: I should say, I'm open to the possibility of the Helmsmanship buff being an issue. This specifically - it affecting Remnants - is something I was aware of, and kept an eye on during playtesting, and it seemed fine, but even so, that's definitely something to be wary of. But also, there's a difference between "this changes how you approach the fights somewhat" and "it was a mistake", though both could also be true at the same time
(Edit #2: Hmm - escort package builds seem in particular ripe for running out of CR, no? I guess it depends on the specifics, but if one takes ships with low peak time, and then tries for a line-of-battle approach that negates their speed advantages... I could see how that could be a failure mode of an Escort Package fleet, is all I'm saying, so that makes me wonder.)
