I want em just as much really, even though they’d fit a neutral race just fine.
With that said though, the amount of effort it takes to turn npc races into playable ones, it’s a tough sell.
There’s some demand for a variety of races, from ogres to old allies like kelfin and jinyu/ankoa, to sethrak, arakkoa and naga.
A better alternative I feel would be to simply to improve how the reflecting prisms perform and/or let people simply model swap ingame. May not be the most polished option but it would offer you a dozen of things to look like and roleplay as potentially.
Have a look here if you’d like to throw your voice into the other discussion.
A sethrak thread is also linked below for additional resources if you want to give that a read.
