I do understand the nerf to this wonder. the way the excecuted that nerf on the other hand is ridicule, especially if you read there explanation which is a pure lie.
Lets start at the beginning, the wonder was hardly build and leveled because the gain in goods was originally way way way to little.
Then the new version came. this version gives us a lot of goods, so many to be precise that with my kinda insane production on my main account I still aquire 2x 3h full production a day from NH.
It's not hard to see that this created a imbalancing effect which is what they noticed.
I would have agreed on a nerf if the halved the rewards. that would have made sense. and I would still aquire an aditional 3h daily production, which is not OP but neither is it bad.
This is indeed icm the mobile version of NH an awesome way to promote NH, which is now totally gone.
Now about the grand big lie. i'll assumme the not the brightest chap on the block who calculated this. forgot to split out the data.
Most likely they just looked at all the NH done every day and then divided that by the brilliant number of players on the server (including the dead ones, or the ones without this wonder)
It then makes sense. because that could easily create a number like 32 visits on average a day. in that regard the message ain't a lie. but every active player who knows how the wonder works and uses it, especially when combined with the mobile version of NH. this wonder was pure gold. a 90+% drop is not a little less. it's massive.
Do not forget that these incentives are massivly important for the NH system in general.
If I look how people respond to NH, if I quit giving NH the amount of return slowly drops as well. once you start buffing all players again you also see the return rate rise again. so it's very important that the super active players are incented to do NH to as many players as possible, because this also activatates the other players as well to return the favour.
Without the active NH players the NH dies out again just as it did before the wonder change.
I get a lot of messages from players like, hey dud I now can buff you back as well I finally scouted towards your place.
Or thanks for the NH every day, unfortunatly I cant return it yet, but i'll work hard to get there.
