Their most common ability was actually a lack of level limits. Not the best way to differentiate I admit, but better ways have been thought of since that don't require the game to have ASIs.Humans are amazing in 3e onward. Free skill and free feat features are amazing. It's only in AD&D where their most common ability is "you don't qualify for anything better, you can be human".
