If you have no friends/guildies that can help you. Don't do Amdapor/Wanderer's Palace. You get jerks who rage and ragequit. Just do Castrum, I find it more quicker. You occasionally have to teach people though every now and then. And sometimes you get jerks that want to skip everything. Don't dare let them control the group telling everyone to skip cutscenes. I find it super rude. You have plenty of time to do it.

And dont rush them. I honestly say take your time.
