Which Class is the best in dmg i was thing of being a mage... cause i love raw fire power is this a good choice....

i think you go for the wizard
because they have
LORD OF VERMILLION
FROST NOVA
NAPALM VULCAN
METEORSTORM
ALL of this spell are stronger than the sage
because if you used sage you'll just use speelbreaker all the time
and other skills will rely on your party mates , friends , guild mates and others
so wizard test is free
but sage test is not it might be around a 80k or maybe
so wizard can demolish powerful strikes you know;) :)

and also the spells like
FIRE PILLAR
AND MANY MORE
you'll see you'll be the greatest wizard if you use your elemental skills wisely!
and pick whats the best? is that right
