I was surprised at the prevalence of half-elves. Is it just for RP purposes or do they have more of a mechanical advantage than I realized?

are very good stat mods, for bards, paladins, sorcerers, and warlocks.
Darkvision is nice, and the two extra skills is just nice for everyone.
IMO bard and warlock are two of the most powerful classes in the game and half-elf is the best race for either of them, because they don't rely on feats to be good.
So yes for me it was purely mechanical when I choose to play a half elf bard.
