Yes, I know how it works. I have a friend with a house who takes breaks a couple of times a year and as a tenant I keep an eye out for the timer popping up in case his break is lasting longer than he anticipated.
No, the last thing I want is another UI element cluttering up my screen. I don't need a constant timer on display because it's irrelevant to me. I actually use my house so I'm in no danger of having it demo'd unless I stop playing, in which case a timer on display in game is useless to me.
It's no more difficult to open up the Timers menu once a day, hit the Estate button and check to see if a house is getting close to demo than it is to actually go to the house and walk in it to reset the timer.
Use the house. Problem solved. No need for something else cluttering up your screen.
The timer is already there.
You know how I mentioned my friend above? He's been focused on WoW since the expansion release. While his subscription is still active, he hasn't logged into FFXIV to play since Battle for Azeroth was released. Guess what showed up in my Estate timers yestrday (image taken just before I'm posting this)?
We're absolutely getting into hand-holding territory when someone can't take 10 second to flip through a submenu on their own to look up information about something they presumably care about and they expect someone else to bring that information to their attention instead.
And it would be totally unnecessary if they were simply using their house in the first place as SE intends. If SE didn't care whether or not players were using their houses, there would be no auto-demo timer based on house entry. It would have been tied to active subscription.
Let's stop enabling the hoarders who are wasting limited resources that others would be using if they had the access. Let's start encouraging personal accountability instead.
