An oldschool, core version of the PvP archetype. Its role is to roam the map and +1 fights, quickly bursting down targets. With enough experience it could also win some duels, although that's not the main focus here. Scepter/Focus FA is one of the harder Elementalist specs to master, but the core version actually has better condition removal than other iterations of FA which should make it a bit more forgiving to play.
Core Fresh Air isn't just some stripped down version of an elite spec build - being able to run Fire for extra damage and cleansing makes it quite strong in its own right.
Being a core Ele build it's available to F2P players who are trying to get into GW2 PvP for the first time.
