@FieryArien As a min/maxer myself I completely understand, and set buildings are a great example. Old sets were designed in such a way that you HAD to get more than 1 of a building in order to get the full set bonus, so that was probably the design intent...right? Maybe? I don't know. I also have no idea if the devs intended for me to be able to replace 6 max level gem factories 10 residences and 5 workshops with half a dozen itty bitty sleds. That plus all of the rest of the set, in total I gained about 70 expansions worth of goods production on Beta which is obscene. I seriously produce over 3x the goods that I used to. Your 17 WW might get you 8K diamonds, but in those 100 days I'll make over 10,000,000 gems...so who exploited the event lol The problem is that we never know what inno has planned. Maybe the costs of techs are going up 300% in chapter 14. Maybe they are going to massively rebalance something else. I posted everywhere that I could how awesome the sets were this event, including on Beta 2 weeks before it was released on live, so if the devs wanted to nerf them, they could have.
