Green Knight said:They don't need to. Their own racial Perception bonus is better.
Who said that the skill bonus is racial? Maybe it is (maybe anything acquired due to race is considered a racial bonus). But, the text we have so far doesn't actually state that yet. A general racial section of the book might state that. But at the moment, this is just an assumption that you are making (shy of hard data). It's probably a reasonable assumption, but we just do not know yet.
Not only that, but why would elves develop (i.e. evolve) an ability that helps non-elves? It seems a bit unusual.
Green Knight said:Would anyone really be able to notice something like that from 30 or more feet away?
Semi-blind allies at 25 feet see the ears twitch. Sharp eyed allies at 30 feet do not.
My only point was that this type of explanation does not make sense. It is a bandaid to try to explain why an inexplicable ability exists.
And, it does not explain why an enemy cannot notice the same thing.
Group Awareness: Is it psionic? Does magic stop it? Does it occur when the elf is unconscious? Does it work through cover? Does it need line of effect, or does it work like a spread? Can the allies use it to find the elf if he is nearby and hidden? How about if he is invisible? When is a newly met creature considered an ally and can gain the benefit?
The problem with "aura-like" abilities is that they create game questions. It's fine if the rules handle most of these questions, but if they do not, it just opens up a Pandora's box of posts on the rules forum forever.
