My personal is ranger since i like to be behind and attack/kill, but if u have factions ritualist are best bet since u can kill much faster and u have those "things" to help u on ur way
if ur going ranger go ranger/ritualist since its nice combine till 20 with helping buffs from ritualist and quick kills from ranger, I got 1 sweet bow i can give u if u want to its kinda expensive but i give u for free, I'll be home at in 4 hours, so ur goung to up or tell me when u can and give me name
