I'm thinking that these leggings weren't lost on accident. ;)
Seriously, these probably shouldn't be no drop...they would be great for twinking, but at the level these can be attained, most druids will have better. They aren't THAT bad, since they do have useful stats, but there are so many great leggings that aren't no drop, that i don't see these being looted very often.
I think these could fill a small niche among druids. They could be useful for druids who only have acrylia studded leggings or worse and maxed wisdom, or for someone who is relatively new to the game, and has advanced in levels fast without accumulating much cash for equipment.
Experienced players with a guild will probably have better.
