I suppose one argument is how much Veracor would disrupt the market if they were granted retroactively. I think he hit 40k vet levels?
Luminara is being harsh, but correct. This would have the potential to disrupt the purpose of the PA. What can be done on one character, gets multiplied by someone then doing with multiples.
I don't know about others, but I tend to play an alt for some goal of that character, but I rarely pay attention to the rewards timer since it's not a factor.
Mostly because doing something repetitively is boring.
For rewards past vet level 100, by that point, most rewards are pretty meaningless. Especially if you don't have many alts.
