Basicly, it depends on you.

To me, Berserker is the best, since at level 10, Having Savage Strike, you can do critical
hits with 50% chance, doing Ravage while using SS gives you an advantage.

To my friend, he thinks Knight is the best, at level 10, you can already wield 2 weapon
and hit over 150each per strike, and the rapid attack for knight is pretty strong when
wielding 2 weapon.

I don't know about Alch. and Druid.

But, you should really try all of them.

i think the alchemists is the best cause its a great person to use on the last boss and
all the bosses you can use bombs, turn enemys to your own partner, use lightning, use
poisin, shoot fire, and BEST OF ALL... YOU CAN SUMMON A GOLEM TO HELP YOU IN YOUR QUESTS.
ITS SO FREAKIN AWESOME CAUSE HE TOTALLY BEATS THE CRAP OUT OF EVERYTHING. ITS A GREAT HELP
WHEN YOUR SURROUNDED BY MONSTERS... TRUST ME!

i know that all of you really like knights becuase it is the most cool of the coolest and
it have very AWESOME skills and super weapons but my answer to your queation is on your
heart and the INSTINCT OF THE GAMER.....

all of them are good but knight i think is best

its how u use it,not which is best,just use what u can use easily and my cousin lv to 20
in 4days and he's using a knight,he uses the skills and i see him died less than TEN
times,make sure u hav good stats and skills to be the best =P

The knight is best cause he has a killer defense and sick attack

Dark knight is best because he can stand specially if ya have good def.
