With these Watchfire Upgrades, we'll now need Ritual Flame Upgrades. Ritual Flame, being currently not upgradable, is strictly worse than having two Watchfires for the same use of space.
Other than these minor complaints, I'm enjoying the event so far. It seems to me that the Colossus is an OK use of space at level 5 or 6, and becomes good at level 7, and is very definitely worth it at level 8.
Ritual Flames will probably stay the same. I've said this about the Fountains of Youth versus Wishing Wells: the GE equivalents of special buildings from events generally tend to be a little worse than the buildings they're based on. So the Terrace Farm has a huge footprint compared to the Bazaar, and the SSW is slightly bigger than the SoK. Now we've got WWs that can be shrunk down to a smaller space, while Watchfires can get a 50% increase to their defense. I think it's more likely we'll see a boost to the Oasis to make it more desirable than the Tribal Square than any improvement to the Ritual Flame.
The Colossus is pretty good, but I agree it looks bad on low levels with all that scaffolding around it. With these upgradable buildings, I've mostly left a few upgrades in my inventory for some of these buildings to level them up when I advance an age. I probably won't do that with the Colossus though.
