In my attempt to make every skill, feat and spell usable at least to some extent, I realized that for skills such as Spot, Listen or Concentration (for melee classes) to be usable in PVE, the AI opponents need to be capable of sneaking and taunting.
Frankly, I never actually met an NWN NPC that would either sneak or taunt, so...
1) Is it just me, or do NPCs never do these actions by default?
2) What other abilities don't they use (but should) rendering some skill/feat investments pointless for PCs?
3) Does Tony K's AI allow NPCs to do these things?
4) Actually, is it possible at all to script AI to fix it?
