I think they should be shorter than the females. Not like dramatically so, but noticeably. Like you could still make the tallest man-bun taller than the shortest fem-bun, but generally i just think they should be shorter.
Every other race has the males at greater or equal heights to the females. One race can be the opposite for once. Not asking for Au Ra dimorphism here, i still insist that was too much.
Just my 2 cents.
Edit: Based on a previous post, their average height appears to be just taller than the tallest possible midlander which is an inch taller than the shortest possible female viera. Which
i think likely implies that they will be just shorter than the average female viera.

Someone put a lot of effort into making this with a midlander when they should have done it with an average height female viera.
