Tainted Battleworn Morning Star (druid gear ?)

[klw]

The courier's spawn rate isn't that low. Maybe 1:15. It's the rarity of the ring which is what turns the camp in to a slot machine.

You're also mistaken saying the mobs con blue to 30. Most of the PHs are 16 tops, most lower. By the time you are 23 it is really difficult to squeeze xp out of the camp.

I'm surprised you believe clearing half a dozen or so PHs at the same time is going to be so much slower than one at a time which is generally done for the purposes of 1) ease of maintaining a confirmed ph, 2) avoiding adds and 3) not interfering with lower levels that might be XPing in the area.
