Tremendously irritating. No mas, por favor. They are flightless Cliff Racers with more lives than a cat and the ability to summon Yogi, I can't say I understand the overwhelming support for their return.
I disliked them very much also. The problem in Oblivon was that they were
everywhere. Not just outside but in caves and Ayelid ruins too (which never made much sense)
The concept art would seem to indicate that they
are making a return though. If that's the case they need to re-work them so that they only appear in dense woodland. And as tree spirits, they should 'peel' themselves away from the bark of trees, catching woodchoppers unaware.
