I have a suggestion for the neighbor help. First a little background. I have a very clear message on my banner, (that almost no one reads) it says, "Main Hall ONLY, please". Yet, 95% of those returning my daily neighbor visits, as well as several people in my own fellowships , only click on my culture. Before you say anything about there being a limit to Main Hall...I know about that, and I'm on the game enough that my limit is not nearly reached, so that does not apply here. Folks click on culture because it's the closest one. That's a fact. So those of us who don't want or need culture, take a loss. That "help" is just a neighbor helping themselves and not bothering to return what's wanted or needed.
I would suggest that we be able to simply put a heart on the help that we want, either Main Hall, Builder or Culture. The same way we already do for our Ancient Wonders. How hard would it be to add a line on the popup box, where we could tick to show preference for the help we actually need? If the person has no preference, then they can simply not activate a heart on anything. Just like we already have the ability to do with our Ancient Wonders, now.
Many banners are a jumble that make them hard to read and understand, many players don't bother to read them anyway, and I don't know, but I think that depending on what device you use to play the game, banners may not show up or be harder to read anyway. But if we could 'heart' our preference for visiting neighbors help, I think it would help a lot to fix this issue.
Final note: If you're visiting a neighbor and give them culture, when they ask for Main Hall, you are not giving them anything at all, if they don't need culture. It's just wasted. There are those of us who keep their culture at the maximum level. So any culture that a neighbor tries to give, is just throwing it away and giving us nothing. Lastly, if you are requesting Main Hall on your banner, but you give me culture or builder, I will not return my 'help' to your Main Hall! You'll get something that you don't want or need, just like I did. LOL!
