I think some great races have been rendered quite unplayable (especially at upper levels) by racial weaknesses to damage types.

For example, nereid. That's a race that is very, very, very evocative and stylish and would be great to play. However, it has a weakness to fire, which means very popular damage types like fire, elementalist electricity and elementalist plasma will do immensely more damage. Nothing about the race remotely evens out such a drawback.

There should be racial drawbacks, but a "Be ready to lose all high-level combats with anyone sensible to adjust to your race" is way extreme. Upper-level combat is almost entirely determined by critical hits, and weaknesses to damage types basically enhance critical hits against you in that damage type.

Various other races have this problem...sword-demon, seraph, dauthi. It makes them basically sucker races, played by people too inexperienced to understand how consequential the drawback is or people who are purposely giving up on upper-level combat.

It would be nice if these races were re-examined and maybe adjusted such that the weaknesses to a damage type are removed and replaced with some other, less extreme drawback.
