It's been long enough on the 75-25 split of ward allocation. The Empyreum FC wards have the vast majority of small plots and a noticeable amount of medium plots still available (on Lich anyway). Any vacant plots in the FC wards of existing districts have been vacant ever since they were vacated.

This split can end now, all the actual FCs got a house and there's an uptick in small FCs that are basically just solo players getting a housings (I know multiple people that started FCs to get houses and then removed the members afterwards).

If it takes an emergency maintenance to change the allocation, then do it, don't hold it for an actual patch like 6.18 (or w/e DC travel is) or even all the way to 6.2.
