Please let me redo/change personal story.
Currently my only options are to be permanently ill-content with my choice or delete and remake my characters and spend months leveling up again. Both are very aggravating options.
But I would be completely happy sacrificing everything I got and playing the story from the start all over again if I got change those starting options.
As much as I empathize your desire to change the past, I cannot read the last part as anything other than; ‘You are happy to start again with a new character’ ?
Leveling doesn’t take as long as you would think once you’ve done it once, it can be quite fun and fresh if there are any zones you haven’t been to before, especially if you transmute your new character into some nice high end looks. 
It’s not only the leveling. Its the full exotics I would have to replace and all the dungeon grinding I would have to repeat. It would be a very tedious and unpleasant experience to have to suffer only because I had no way of making an informed choice when I original created my characters.
If you don’t mindme asking, what exactly are your gripes here?
I’ve done the entire story so don’t worry about spoiling anything…
Do you even lift, bro?
