Oh Wise One
I don't see any reason to keep it since I have level 10 Panda which is almost the same. T2 inventory is pretty ho hum anyway.
Panda is a 48-hour collection cycle and Gingerbread is 24-hour, but I have both out.
And maybe tier 2 is not a big deal where you are located for trade on your servers, but where I am on Arendyll, the tier 2 goods are the hardest to get of the three tiers, and past events that people seemed to like more, such as the one with the Krarak and Kirit set buildings that give tier 2 goods, were not nice to me at all for getting those set buildings, so crystal and scrolls have always been the lowest of my nine goods. I am happy to have one Gingerbread at level 10 and another at level 6, eventually to be level 8 after the next FA. I really wanted them for the crystal production, though scrolls are not a problem now that I have four almost complete Moonstone Library sets from the Spire.
And I am looking forward to whichever event later this year will have the evolving building that does the same thing for tier 3 goods that the Mermaid does for tier 1 and Gingerbread for tier 2.
I do also have to say that if these buildings did not include population, I would have a much harder time keeping them around. The pop is what makes them into "worth having" to me.
