How do you level alts quickly?

[seekified]

For tank/healer jobs I do dungeons runs all the way from 15 to 50. For my SCH I got tired of people killing me in Aurum Vale so I did the last level in twenty minutes doing fates in Northern Thanalan.

For DPS jobs, it's not as easy... hunting logs, fates and leves, mostly, while making sure to hit the challenge log bonuses. Leves tend to be faster than fates between 20 and 30, because South Shroud is both awkardly hard and devoid of people a lot of the time.
