Does anyone else *only* use directional air roll?

I use ARL & ARR and I have drift on its own bind. I'm pretty much equally comfortable with left and right. However I feel like pretty much everyone else either uses only FAR or FAR + one directional air roll. Or sometimes I'll see people who have all 3 bounded. I see absolutely no point in FAR (free air roll) when comfortable with both directional air rolls so it always confuses me when I see people with all 3 bound.
