how will there be a lottery and a first come first serve for housing?
So you can be there before all other and still get it? And then the lottery people will just have to sit back and sulk again?
I suggested a lottery system ages ago, one that did not even constitute a major change to the whole system as it was. It was basically that you set a timer, and all that came to the plot from its avaliability to the timer actually made it possible to buy it, would be allowed to put down gil for the plot and thus have a lottery spot.
Ones the timer went off, it would close and draw among those that put down gil.
The winner got a mail with the deed, and the rest one with their gil back.
Then they could go on and try their luck again next time. Ofc taking in to account you can only go for one at the time, so people will be encouraged to go for the one they really want and not just swap about ones they get one.

But all we gotten so fare been half arsed, rubish and made so people would ruin it and just mess stuff up, and in the end the housing was just as horrible and you would still end up clicking buttons for hours on end till your wrist swells up and your elbow hurts. And yes I have been there... twice! First one was 8 hours, and you manage to hear quite a lot of podcast in 8 hours while clicking.
The other one was 10 hours clicking. And after that my wrist was swollen, and I decided to not bother with housing one bit ever again till they made it less dangerous for my poor wrists. (and yes I could have stopped, but being like 90% of players, I greed for a house to stuff my trophies in to and make a little bit of Eorzean decoration show out of.)
