DFO General Chatter/Community Discussion

How many hours do you guys think a new player would take to reach the challenge levels? I just reinstalled after playing briefly maybe a couple of years back. Only got a ranger to level 20ish and was never good at the game, so I want to be realistic about what level I can achieve without losing out on extra rewards. Also, can you recommend me a flashy class that's good at soloing? I'm going to guess Chaos since it's new, but I would appreciate your thoughts!
