Something what isn't really needed is that they say if you want to ugrade all blocks that you can keep your recourses for shiney and upgrade them instantly but the only thing want upgrade them all without using shiney. I don't even want to uprade them instantly, the only thing I want is to upgrade them so that I don't need select every single block.
It should be possible to help repair buildings too because it doesn't makes much sense if you can help to upgrade something but not help to repair damage after an attack.
