What's the fastest way to make farm characters?

[Bunz]

Which class is the fastest to level up?

Where should I level them?

DN Guide says

1-10 Story line
11-16 3 Birds map
16-24 ACL

Any tips/suggestions?

I used assassins. As soon as you get 6, equip the costume and from there you oneshot everything.

Specialise as shinobi and skill all te damage skills, skip passive and put into dash whenever you can.

You should oneshot everything in ACL once you get iron applause.
