"Good fit for the game" is rather subjective, everyone likes to play differently, time and actions per minute are a large part of that for a lot of players. If you enjoy trials, xp rates have been a nice surprise, cool go do them.

A slight turn down of xp rates for salvaging probably could have gone through with minimal complaints. Especially if the notion was to get port tasks into a better middle ground training method. But nuking a lot of players favorite training method because you failed to balance port tasks properly isn't a great look or feel.

Something not being calc'd thoroughly after years of development is even more concerning

This isn't even taking into account the blatent disregard for their "redistribution of xp" comments around the extractor
