I wound up running out of quests to do from WPL/EPL/Winterspring. I did every kill quest, and any quest where you deliver something or go and pick up one item. I skipped every collection quest, even if only 1 or 2 items needed to drop, I still skipped it.

At around 56 I finished every quest I wanted to do in those areas and found myself stuck. So I headed off to Silithus. That had about 4 quests for me to do. One of those was a collection quest that had you collecting 10 encrypted twlight texts. So I sucked it up and did it. I'm only 4 boxing, so I only needed 40

Needless to say it wasn't that bad, and the drop rate was pretty good. After finishing all the desirable quests in Silithus I was 70% into 57. So I headed to DM East and grinded that until 58. Only took one run before I dinged 58. Then promptly headed into outlands.

I plan on doing Outlands until 60, then going back to Old world and doing Strath/Scholo/DM for a while. I attempted Scholo @ lvl 59 last night with a few greens from the Outlands. I was burning the mobs down really easily, but since my pets are slightly retarded and I wasn't being careful, I wiped about 3 times. But I'm sure with more patience and being more careful, I can easily clear it.

By just getting about 4 pieces of outlands gear, my hunters went from 3700 hp @lvl 58, to 4900 @lvl59. My Attack Power almost doubled too.
