Sheesh, everyone advising one legendary quest after another. While these can be done with some ease, I would not recommend them to a fresh lvl 60.
So, go to Northern Hold, and progress along the Beorix-related storyline until you unlock Race Vemundr Race. This quest can be done with absolutely no gear, takes roughly 2-5 minutes to complete (Depending on skill), and yields 2 classic legendary chests, so it's excellent for gearing up.
An additional easy collection of quests is the Ambrosia Obsession collection in Babylon - After completing the first 2 quests in Babylon, you'll unlock a series of Challenge quests to collect gold. Upon completion of that short series, you unlock the Ambrosia Obsession collection. While it doesn't reward much in terms of items, it DOES reward quite a bit of Gold and EP quickly - You are looking at 30 minutes of questing if done right for 10-15k gold depending on rewards, as well as roughly 40 or so EP - Pretty good value for those two currencies.
Moving on up in difficulty a bit, once you finished the full Beorix questchain, you unlock 4 City Conquest "legendary" quests as well as Beorix Returns. While completing the various bonus objectives on these quests is quite difficult solo, actually completing the quests are quite easy - Though I would suggest lvling up Persia until you can acquire Taxes, it makes the City Conquest and City Defense (And other similar quests) much, much easier.
