Yes, there is a little bit. 

For instance. Aquamarines are assistance and protectors. They are placed in Kindergartens to lead the newborns or placed with the Scintist in case anything happens that need healing abilities. Leaders use them to communicate orders in battle or as strong protection/bodyguards. Either way, they are helpers and not looked at as too much but they aren't low either.
