Also, I see no point in having such alike behaviors aligned as wings. If you already have one behavior, why do you need an altered version of that same one?
To comment on your dislike of the 9 and 8 wings: having met several 9w8s and an 8w9, I have seen this balancing act in motion, and have no problem with this wing alignment.
Absolutely. But why would this contradict the system I'm supporting?I think another thing that should be considered is people being different types along the instinctual variants (which are direct parallels to the FIRO's three areas of interaction).
I'm also curious as to your opinion of the triads, since you seem to think they're not grouped well in the enneagram.
