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.
I have been doing this but because I want to keep the party on guard. Also I think villains who think they are the good guys or doesn’t think what they are doing is wrong is better than I’m evil because the plot needs it.
