On the issue of Quiet in MGSV. I actually haven't played the game yet but I've got it in my PS Plus queue. Now that the Pro patch has come out I was actually interested in playing it, but the character design of Quiet is actively putting me off starting. The character's clothing is ridiculous and cringy, to the point that it'd make me a bit embarrassed to be playing the game. My wife would rightly flip out about how dumb it is if she saw that in the TV. (And yes. I did read the story reason why she's dressed like that)
Just an example of this sort of thing totally backfiring. Skimpy crap like this or Xenoblade Chronicles 2 actively puts me off playing. The designs are just too dumb and sexist.

Outside of the mission where you essentially have her join your team, you can choose to never bring her on a mission, and a lot of the "bad" quiet scenes wont happen if you don't bring her along and level up the bond (I quoted bad because I liked all of quiets scenes)
I think quiets issues are overblown for that reason, she can be largely secondary if you choose to have her be
For me, she was my one and only buddy I used, I maxed out our bond and enjoyed the chopper rides, cut scenes and her buddy perks
