On original classes in BDO (Valk, Witch, Ranger, etc.) and a couple of the earliest added (Kuniochi), the butt and thigh sliders actually do something. You can give your female characters some pretty impressive thighs, and at least respectable (but not proportional to the max thigh settings [which is understandable, considering the largest thighs are a bit on the obscene side]) rear ends. 

But this isn't possible on new classes. In fact, on characters like the Drak and Corsair, the thigh sliders do almost nothing - a slight thickening at most. And the butt sliders? Well, they actually do nothing at all - you can push them all the way to the right, and there isn't even a trace of alteration to the model.

I do, to an extent, understand wanting the pare down the impact of the butt/thigh sliders (provided a designer making these decisions wants his women to all be built like size 0 runway models), but to remove their functionality entirely is just... weird. Like, why is it okay to make my Valk some size 12 or 14 curvy goddess, but my Corsair doesn't have the chance to be even size 2?

In a similar vein, I get pulling the option to select different voices - hauling in a bunch of voice actresses (or paying one voice actress additional to throw her voice a bunch of different ways) is expensive... but is there really some cost/income analysis when it comes to designing a model to handle a slightly-expanded derriere?

My guess is no... which leads me to conclude that this some kind of weird, mostly-silent crusade by a person in charge waged against curvier game model options. And that's... really a shame. Because if you wanted that size 0 Witch, she was always there for you. And the opportunity to make a curvy Corsair or Drak should similarly be present for those of us who want it.

Amen. #JusticeForMissingButts

Yes give Woosa or Maegu thickness please or we eat shai.

Welle truth to be told: This game isn't a AAA title going for top quality anymore (what it used to be), instead it is now in customer milking mode. 

i support this 100% pls remake the slider for all female class and give us more buns ang thiccness.. cause that youre doing right now is limiting the players freedom to customize the characters and just forcing the developers beauty standars to players. if you ever remake the sliders then more players would be more enticed to play other classes and you make more money cause they will buy more costumes for those new classes. its a win win to be honest so the question is why wont PA make the slider give thicc thighs and butt even though they have the power to do it like what they already did to the older classes?

Only Ranger, Dark Knight, Sorcceress, Valkyrie, and Tamer can have thick thighs. Guardian has a unique body for muscles and Lahn has the smallest fram of all the female characters. The rest of the female characters share Maehwas body type size.
