If you want to play in Dorastor, then the end of the Third Age is the time to do that. If you're going to play in the Second Age, then there are much more interesting places to go - Pavis, Zistorwal, the EWF, the Golden Sun Dragon, Feroda, an intact Seshnela, etc.
*Update*: Maybe I'm wrong about Dorastor, there probably is fun to be had there.
