I only log into MW 3 times a day(except during events. I'm on a lot more ofton during events) so my plan is to build the 8, 12, 24, and 48 hour buildings but I also have other buildings that don't collect in those time periods. So my question is do I sell those buildings since I won't be able to collect from them every time making them easy raid targets or keep them but not upgrade them any further?
