You pull moderately and get your s rating killing bosses first try. What are *you* smoking that you think that getting s rating without a mage is impossible?basin most certainly requires aoe or cc or something. you cleared basin with sin archer - it's a lot harder than with mage. those mobs there hit a lot harder and the pulls are dangerous if the tank isn't familiar. So you say they don't require aoe, what are u killing the mobs 1 at a time? if so you more than likely didn't complete it unless there were no wipes at all and even then..
All the dungeons require aoe to be the most efficient in both time and kill count - what are you smoking?
