On beta, obviously I am keeping the Arc for the contribution bonus for donating into my mates' GBs and hoping they will do the same so they can donate to mine. I am thinking about deleting the 'traz since I have buildings that give out rogues and I am mostly using NAUs (steel wardens and sentinels) gathered from QI and event buildings that give them out. Happiness is way too much (400k I think) so deleting this building won't feel like I am missing anything.
I wanted to keep the SV, CF, AIC, BG, and obviously SC as they still have some value to them. All the others I will delete (HC, TA, TT, FI, Obs, Galata) to make room for more QI and event buildings. I will probably choose a building to dump FP onto once I am bored with the rest for FPs, and by then I am hoping to go on a strict low FP diet which will probably be hard in the beginning but I already had in mind which buildings I want to put up for GBg statuses that hardly have any fps attached to them.
With the bullsh*t that I had read about the GBP, I feel it is not in my best interest to continue engaging in the feature.
