Your signature always fascinates me Rokke.
Well but let's have an honest discussion.
1. You're comparing job to race and gender
2. Your job doesn't have a physique requirement
Race physique and looks is determined by the environment that race has been living in for over thousands of years. Lalafel fit in perfectly in the sands of Ul'dah and the plains of Vylbrand.
Now, could have Lalafels been added as jungle warriors? Sure, but this is where we hit a wall; female viera exists. This not a brand new race that doesn't have a counterpart to inform us of what the males would look like, so much so that we already have art for them.
You can't run away from this
The problem is you can't reach that jungle warrior description going skinnier than male Elezen.
