I agree. I dont buy gold often and the gold I have now is from gold videos and offers. With that gold Im going to buy the buildings. Even if I were to be gold free, I would buy a vault or 2 JUST for the +1 building upgrade and LTBs. It is worth the 100 buckss because you gain a really good boost ( one I did not have yet ) and a huge income per hour. That will let us do more in Frontline and afford the bigger LTBs. Now we can have 4 of each of these buildings. Its a game changer and increases the economy in the game, since more players will have good buildings to raid.
