the point what he wanted to say , mage have insane burst , but then lack on dps , on those screenshots he did like 10 mil dmg on each , which is pretty mutch full burst , and like 400 k dps durring that burst is bad for mage, he cant hold such dps for long. sry for offtopic
and yes for pure single target fire have higher dps output { durumu - also bcs of movement } , jikun etc. pretty mutch all bosses on ss
