Why do FCs get 75% of the wards?

[Yodada]

Mist P19/20/21 - P49/50/51 are a good example of the most abandoned smalls that are just used by dummy fcs with one player in them, feel free to take a look at them when you log in and report back here. and that I do know from my own eyes because I checked it several times a day for months until eventually one came up.

And even then 275 of 1678 FC Houses on Zodiark having less or exact 3 Members. This accounts for a total of 16,38% of all FC Houses or of 4,77% of all total available plots before Patch 6.1. If we assume that all of those 275 are just abondened shell FCs and not one Single Player FC which uses their FC-House on a regular basis i'm still not sure where your 80% came from.
