Just to make it clear, making steam from water and making mist from water are two different things. Just seperating water molecules will give you mist, however steam requires a fair bit of heat to make. That would take fire runes, or actual fire to do.

As for controling elements in general, yeah, I believe most experienced mages can do this, and a good amount of us already RP in this fashion.
