Best is to play mage style on ES with summon and if u want to box u can box bd for mystic + conc or prophet for bers.
But mage is a lot of -- adena, u need to be rich playing like that after 65.
But if u play more like 5 h per day go for fighter build, mage is intense, u need to spam like 4-5 buttons nonstop (aqua swirl, summon attack, recharger, next target, and sometimes heal)
