A caiman scowls at you ready to attack
 

Whats this?
These guys were all indifferent on live.

(IIRC they weren't even social)

they scowl but don't aggro, and they're not social.

They were dubious on live.

Is that even possible? Isn't that tied together?

i dunno why but that's how it is on here :)

From launch throughout Velious, the crocs in oasis always acted like this. We went out of our way to ensure that same functionality.

This probably changed later on live, but there are various instances of 'scowls, but doesn't aggro' npcs in classic times.

Death beetles in unrest, for example, should scowl, not aggro, but assist normally.

crocs/caimans in oasis should scowl, not aggro, and not assist.

Scarecrows in West Karana scowl but are not aggro (or at least weren't on live). Any green/non-exp should not aggro even if scowling unless you sit nearby. Decaying skeletons always aggro even if you're level 60 independent of sitting - they will attack. But, factions on P99 are screwy, so don't assume anything from live.

All of this should be working. If it isn't, we will fix it with provided bug reports of how its not functioning.

Crocs scowled iirc, caimans were non-kos but I am unsure which con. Dubious or indiff I think, looking for ss.
