I like this, I'd advocate for a fruit-based task system - although I suppose the exact fruit ranking would depend on the team.

- easy peasy: lemon

- easy but needs careful handling: kiwi

- regular but boring: red delicious

- regular, who wouldn't want to take one of these?: mango

- large task, risk of splash damage if mishandled: watermelon

- tough to crack, needs time or a hammer: coconut

- technically we'll do this, but not really our job: tomato

Edit: I am sad that emojis aren't allowed in comments, though it's understandable.
