Every time people lament changes to the lore that amount to "not every member of species X is irredeemably evil" and claim the game is removing villains from it, I think how villains of so-caleld evil species fall into two cathegories: a) bland and boring and b)have something else, unrelated to their species going on for them, that makes them interesting.
Personally, as a DM I get tired of how many different intelligent species there are. It makes worldbuilding very hard. I tried carving out space for each of them, but it wasn't worth it. These days I prefer to just get rid of most races, but it's a bit hard to tell which ones to keep.
