NPC Spawn Issue: Thistle underbrush - should be super common?

[Jimjam]

You mean the fairy maiden one? We did that for quite some time but with no luck. Whats his spawn % meant to be?

Later I hooked up with someone else and just killed loads and loads of scouts (based on a zam post) but only had more scouts spawn.

Might have to try just repeat AoEing all the newbie stuff and seeing what happens.
