You need to remember that HW1C was a LOT harder than HW2 or Remastered. You got far fewer RUs - you had to stay and collect everything on the map and you still had to capture or barely lose anything to reach unit cap by the end of the campaign.
In Remastered you can stop harvesting after mission 8 and have basically infinite resources. DDs are so powerful that they can shrug off everything except HCs - you get enough resources to have all 6 of them before you leave the nebula.
Capturing ships is a lot easier - in Classic salvage corvettes were vulnerable to everything. An ion frigate would reliably kill one if you approached it from the front and an Assault Frigate would almost never miss. DDs and HCs would snipe salvagers before shooting your own capital ships.
Now, you can rush a HC head on with 8 corvettes and almost all the time 6 of them will latch on and capture it. In Mission 10 I just rushed 14 salvagers against the 2 DDs and HC and got all 3 of them without needing more than a couple scouts flying around to distract their terrible AI.
HW:RM needs the scaling or it is stupidly easy compared to classic. I don’t mind having the easy mode available but you have no right to complain - I have played enough campaign to know that the problem is not inside the game.
