Mostly that I feel that the narrative negatives that already exist are enough considering the positives, if we suddenly start losing access to entire characters wholesale because of high corruption we should have other characters take their place.
You want to keep all the advantages and negate any possible disadvantages by additional content for characters with high corruption?
There should be a balance. You lose something and gain something. Big differences between corrupt/pure route give meaning to our decisions and stimulate the desire to play the game again and try different decisions.
Well, that's how it should ideally work.
Unfortunately, unlike corrupted characters, pure characters have not received a single thing that would justify their existence to this day...
In fact, it is quite possible that there is no such thing as a
"pure route".
Maybe there is only
"corrupted route" and
"route where you failed to accumulate enough corruption".
Maybe is corruption good stat that we
SHOULD want to increase, just like power.
It certainly looks that way for now...
Despite what game lore says, the facts speak for themselves.
If low corruption only affects the ending, then there is no point in trying.
Why knowingly deprive yourself of a huge amount of game-wide content when it only affects one thing that you can (if you want) change at the very end with an editor?
