I totally agree with OP.

Unlike your FC though, we managed to purchase a small plot months ago. Still, we were left with no choice other than The Goblet (we all wanted to go to Gridania or Limsa for various reasons).
We still got it only to accomodate ourselves until more wards would be released... which too forever and all the plots were gone in an instant.
Now, we would gladly relinquish our plot to get a larger one in Gridania or Limsa, but we'll never be able to at this rate.

The bigger plots are even more expensive so we need to wait for the price to come down, but bigger FC just grab the lot at whatever price.

Honestly, there should always be a new ward added immediately when they are 90% full.

If the same thing will happen with private housing, the dev's better put it off for a later date and prepare a HUGE amount of wards.
This is just ridiculous to lock out players like this or be forced to pick a location you don't like much.
