Are you trying to get faction rep up or corp rep up?
If your going for faction rep, just move to a new hub, your goal is to just complete a ton of missions to get a storyline, no big deal. Some corps also have multiple hubs in an area.
If your going for corp rep, your efficiency dips slightly, because you now need to go to “Singleton” agents, who are still strung about in space pretty close to each other, they just aren’t all in one station so you lose a minor amount of efficiency making 1 jump to dock at a new station.
And, of course, you can gain rep significantly faster via grouping.
I agree its a silly system at times because its very RNG based, but it doesn’t make the grind take significantly longer when you even remotely try to work around it. The reason people are teasing you is that your resorting to hyperbole which always undermines your own argument.
Go for “its kinda dumb and doesn’t add anything to the game really to make skipping faction hits cost rep” rather than “I want to reroll constantly for missions because rerolls add nothing to the game and not being able to reroll ruins missioning.”
Again, your proposed solution is a non-starter because limited rerolls are actually very important, and the cost of removing them is greater than the gain of sliiiightly reducing rep gain grind, which isn’t even objectively good because it makes reps overall a less important mechanic and makes the advantages of rep more universal, which simply further increases the time investment new characters need to make to be competitive.
