I agree with
@beelzebob666, the building gives way too many fps compared to other buildings. We've been used to around 0.5 fps/tile, with the occasional building giving a bit more. But bumping that all the way up to 1.82 fps/tile for a
regular event building is too much. Unless I've missed a building that makes it the absolute best forge point building in the game (excluding GBs), next closest being the Mughal Temple at 1.67 and Tree of Silence at 1.33. Both of those are already exceptional, but balanced with big limitations (Mughal only 1, Tree very small and hard to get). If a regular event building is able to beat that by so much, it completely messes up the balancing. Some inflation is necessary, but don't go this far. I think at most the building should give 15-20 fps, which is already a big leap from the standard rates.
In addition to the FPs the building also has a very good attack boost, slightly better than the Winners' Plaza for example. At the moment the building is like a Winners' Plaza producing 19 fps(!?). Personally I'm all for attack, but don't think the building should be this good at both. So in addition to lowering FPs, I think the attack should either be reduced, or even removed, depending on how many fps the building end up giving.
Edit: with the latest GE level I'm fine with a building producing a lot of goods, but combined with all the other aspects the building is good at (also units..), it's simply too much. A regular building shouldn't be this good at so many aspects of the game.
