It won't ruin the game. Players will ALWAYS reach for upgrades higher than their vaults. New huge buildings = new huge vault. Nothing has changed in the mechanics of the game, other than we get to raid massive buildings to raid even more money. If you want the big buildings introduced then there should be no complaint with bigger vaults. You can't have your cake and eat it too. I got my ACs and AMRs by killing a bunch of bosses at once, selling a few buildings, growing a palm tree farm, and in the case of the last AMR, just saving up and raiding for 4 days without getting attacked a single time at lev 185 with 55k def....even during the PvP event lol. My low vault/non-gold player was not a factor in buying any of my four new big buildings for over $400 million. The new buildings also help greatly with buying expensive faction bonuses which will continue to be introduced which I'm sure nobody will complain about. Also, stud players will be able to exponentially increase iph faster than smaller stat players, and in turn increase faction bonuses faster, and in turn receive great WD unit rewards, creating even more power separation between stud players and lesser-advanced players. If you don't like the vault, give GREE the WD bonuses, faction bonuses, and high IPH buildings back by all means! Everyone always finds something to complain about, oh brother.
