This will be a disaster for me on Korch... here is why
I have worked very hard to build a reliable list of friends who always visit me (almost) daily. Between them and my guildmates I get visited between 100-120 times per day.
My priorities set in my profile are PSC. I have 7 cultural buildings which get polished every 12 hours, so that's 14 visits accounted for and 8 production buildings which I almost always have on 4 hour productions, so that's 48 visits accounted for. These are almost always done to perfection, so that's 62 visits accounted for. The other 40-60 visits go to my houses even though coins are a low priority for me.
Now with this 'easier' way to do it, there will be no way of setting the priority. I know people CAN visit the city and select a building manually, but let's face it, they won't.
So as a result of this I will find often more houses will be motivated but sometimes I won't have all my cultural buildings polished or production buildings motivated, completely ruining the perfect balance of coins and supplies I have managed to maintain, and often likely leaving my population not enthusiastic.
This will also be an issue for me on Greifental... There I also have specific requests which my guild and friends follow fairly accurately. With this new feature I fear the vast majority will use it and my requests will not be fulfilled, this will make the game significantly more difficult for me and may require me to completely rethink my city design and balance.
Very unhappy with this
