My personal favorite right now, the yuan-ti, is highly unlikely to ever be included unless we see a sequel. Which I'm fine with.

I have issues with the yuan-ti write up in that it's very much of the "let's copy the MM entry" variety of making a player race and I'm ambivalent about some of the features. My personal homebrew of them replaces Magic Resistance with a Advantage versus effects that cause Charm or Frighten (due to having unusual emotional states), dropping Poison Immunity to Resistance/Advantage on saves. Keeping Snake Friendship but replacing the other lineage-spell load outs based on which of the big four snake "gods" their heritage associated with (Sseth, Merrshaulk, Dendar, Zehir). Feels a bit less bland/overpowered and more in keeping with their lore.

But yeah, they're the least likely lineage to be seen on the list.

I do hope all the plane-touched ones get included: Aasimar and Genasi... just because of the amount of plane-walking going on in just the tutorial.
