I just think it's bizarre to have a black dude protagonist in a historical japanese setting.
Why? He is a historical figure. Why does a historical figure in his historical setting feel bizarre?
I've read through the sources on Yasuke and I think it's a stretch to say he was like a full fledged samurai.
Potato potato. Why him being a "full fledged samurai" even matters? The series is known to take creative liberties with history.
Seriously ask yourself why having ONE SINGULAR black protagonist in a series where protagonists have so far been overwhelmingly white feels like "black people getting pushed into games".
Because to me, it sounds like you have seen too many opinions of people getting outraged and because of that you internalized their views without asking yourself why they (and now you) feel the way they do.
It would be as easy as putting a slider to reduce damage taken/increase damage inflicted.
If people want to go experience they can play the og game.
Take Celeste for example. Celeste is a game meant to be hard, beating Celeste is supposed to be a trial for the player, it's their mountain to conquer.
And yet, Celeste gives so many accessibility options you can trivialize the game. The people that need it get to play the game and the people that don't need it, play the game as intended.
That's not to say that Dark Souls should have an easy mode. Just saying that it could, easily, have one. They don't because they'd rather maintain the image of being a hardcore™ game than help people with less time/skill/capabilities play the game.
