Of course GBs like Arc won't but I want to ask the community if they also agree/disagree with me that with the inflationary rate of the event buildings if buildings providing fps and population will become not worth it to level. Also attack and defense boost of special buildings are becoming better and better.
Yes. Innovation tower is already obsolete, I deleted mine earlier this year and it was level 70 paying out about 45 fps, giving me useless population that I already have more than I want, and taking up too much space. That FP loss was small compared to the event buildings with blue galaxy doubling them, or even just on their own a couple of event buildings pay out the same as that level 70 GB that took me years - plus the event buildings give a bunch of other resources that the GB was not, most importantly attack and defense boosts. A whole lot of GB's have been aged out of the game very quickly.
There is no reason now to build Inno Tower in the first place, or keep it. Most people have hundreds of thousands of surplus population from event buildings (I have 800K people sitting idle), and that was the original thing that made the Inno Tower good back in the day, it was a huge space saver on houses. We don't use houses any more, or much of anything from the standard build menu (as I have lamented in another
recent post, a lot of things have been lost in the game that used to be part of the charm and/or strategy of how to balance between goods, troops, FPS, and happiness in each era.)
Cape Canaveral is not obsolete yet but it's getting there fast. I have not deleted it, lucky it's only 4X5 and relatively small, that is saving it for now, but maybe not for much longer. Pretty soon anything that does not give attack/defense boost or help with fighting (AO and Kraken) is going to be out of most cities, excepting things like Himeji, Space Carrier, Blue Galaxy, Chateau and Arc which are support GB's that double other actions or have big payouts associated with them. Even a "poor" day in GBG nets me 200-400 FPS, it makes the payout from Cape very weak - and that's space I could use to put an event building that gets me more boosts plus all the other things I need rather than "just" Forge Points. I recycled all my shrine of knowledge level 2s last year, and have started doing the same with carousels, checkmate squares and royal marble gateways because even those are going obsolete compared to new event buildings.
I agree with
@Emberguard that the holy trinity of Zeus, Aachen, CDM are still safe to remain relevant for a long time, but the list of "essential" GB's is getting smaller and smaller. You could make an argument that if you don't GvG on a PC, you don't really need Alcatraz any more. To play GE and GBG you could get by on 3 or 4 rogue dens plus troops that you win various places (GE, PVP arena, GBG, daily incident chests all hand out troops like candy) and collect from event buildings, especially knights pavilion at 2x2 is pretty close to making Traz and troop barracks in general obsolete.
