Heixing scaling with accuracy is exactly to combat such problem with his basic attack, sadly it is a indirect buff to Ranger, so I will look further for Sweeper soonish, also his skill Sweeping Fire is TOO good and Field of Zero is TOO weak, so I made small changes on them to see if they shine where they should shine.

Powerhouse scalings on some of her skills and basic attack do reduce her overall scaling with Attack Damage to give space for some Armor scalings so you could differentiate White Knight from Berseker in the future, but I'm still tinkering with it little by little, but I found it cool that is it possible to make attacks scale with Armor and White Knight seems an ideal class for such approach.

About Giselle, you are absolutely right, since Sniper already have good sinergy with Critical Damage, Hunter gets hurt very badly, I will give priority to this issue first since I clearly overlooked this.

Haven't tested anything, overall seems pretty good (at least with good intentions). The only things I don't agree as a principle are:
> Heixing scailing with Accuracy if, and only if, it is on top of default scailings. Heixing is already the top damage dealer from middle up to late-game only held back due to overall low per-shot damage; I think to make Sweeper to be less inpractical (it is not bad, just underperforms ranger by a mile) there would need to rework some of its exclusive masteries.
> Same with powerhouse if, and only if, it is added on top of default scailings. She does great damage already.
> Decreasing Giselle attack damage, Sniper won't care at all but Hunter already struggles with damage as it has none of block shred and crit modifiers. It just pushes her to be staler I think.

Yeah that's the thing, I don't want to give too much info in case someone that didn't unlock them comes here.

Then again, you go into the DLC page you will see everyone, but I kept it anyway.

Absolute Unit? Girlfailure? Great you have nicknames for the characters, but it only works if all know what you are talking about.
