Whens my trollyboiz going to be able to stand up straight like the orcs?

All the armor looks bad on races that are perpetually bent over.

I think Undeads are first on the list

undead look better though. have you seen a female troll run? looks like someone put a flagpole up her behind and she just wiggles on each hip without moving the rest of her body. its awful.

Zandalari exist. Upright darkspear males would look really awkward, i think. Like a more gangly slender man.

Also canonically, Zandalari had to force themselves to stand up right until they kind of evolved to do it naturally.

so?
I dont see a reason here for you to tell me “no”.
I want my troll to stand up straight. maybe does daily stretches.

Given how big male Darkspear are? Probably never. They’re not going to let you be three feet taller than a Tauren.
