So you don't want the placard clicking system back. Good, there's hope for you yet.
Of course there are things that can be improved, but there is no question that the current system is completely fair. Everyone gets the same opportunities. That is the definition of fair. What they do with those opportunities is their business, and anyone else's opinion on those actions is simply borne from jealousy.
If someone wants to bid for a house simply to use it as a stop gap with an aetheryte and a retainer bell, that's their business. It's disappointing, but it's fair. You can't tell other people how to decorate their homes.
FC's have multiple people, and therefore they get multiple opportunities to get their one single house, because it's multiple people using it, that's fair, because every FC can do the same thing.
People who play multiple characters or pay for multiple accounts, are entitled to put their bid in for a house on each of those characters/accounts. That's what everyone is entitled to in this system. That's fair.
They're all still playing exactly the same odds, they all have the same deal, all pay the same amount of gil, etc. You can't bot your way into a house anymore btw, everyone's ticket is equally weighted.
I'm not opposed to raising barriers (if they're equal for everyone) to entry into housing. I've been in favour of raising the cost of Medium and Large plots to more closely match the demand for those limited plots.
And if they were to change the rules as to how many houses can be owned per service account, then that new qualifier would also be fair under the lottery system, as it would apply equally to everyone.
As long as the same rules apply to everyone, it's fair. The same couldn't be said of placard clicking, because it could be exploited via autoclickers, and featured the incredibly unreasonable requirement to be 100% present for up to 18 hours straight. Even Ultimate Raiding isn't that harsh.
