This isn't strictly a Pathfinder thing but I like this community.

Basically, there is this meme that Human Figher is a "boring" default choice or sign of an uncreative character. I disagree. Picking out a weird ancestry is not creative. Choosing a human fighter basically means that you get zero flavor from your ancestry and class - so you are forced to get creative yourself. You are forced to give your character a personality, and you are forced to solve problems creatively.

For me, the stereotype is the opposite - if a player chooses an esoteric ancestry and class combo, I worry that their characters whole personality is just their ancestry.

Of course both humans and other ancestries make for great characters if done right.
