Looking to find out who is the best! To see if I need to create a new character or not.

berserker or lancer imo

bersi

lancer

there is a dungeon called kelsaik's nest is easily solo-able for lancers only
you can make up to 400-600k gold when they have double drop weekends

warriors are easy to play

zerker

I picked zerker, just cuz its fastest to farm on

Lancer: Can solo lot of dungeons to farm but takes long time.
Zerker/Warrior: Can skip certain parts of dungeon whereas lancers aren't able to, making them faster.
Zerker: Just does lot more dmg than lancer/warrior and will kill faster.
