I could be wrong here but wood-elfs seem to be on the low end. Perhaps the high exp and iron vulnerability, plus the low cons/str didn't help much. The current wood-elf pluses didn't help other classes that much.

Some inherent ideas to toss :
1. Tracking in the sense that a wood-elf can ALWAYS(??) see where a (semi)sneaking person has fled in woodlands area.

2. Sneak, limited to natural areas only.

3. Nature's passage. Limited pathfinding. 10-20% less movement in natural areas. Not as skillful as a ranger/druid pathfinding.

4. Enhance Natural weapon/armor. Remove the ranger's imbue but give wood-elfs using non-metal and natural weapon/armor a slight boost in properties though not as powerful as the Sylvan's power.
