I currently have a town hall nine farming base layout! While saving up elixer and gold for my upgrades I have been finding it hard to get above 3 mill elixer and gold, I was wondering if I should get the fourth storage and what the pros and cons of getting it is! thanks!
Well if you th9, if you want to keep most of builders working you need to upgrade the gold storage so can save enough gold for defenses.
upgrades costs a lot more, and always good to upgrade xbows to lvl 3 and archers to lvl 6 even if not getting to much strong .
so yes i believe you should.
A spread out TH9 defense with 4 storages also makes it harder for raiders to take as much loot. You should have no problem protecting 4 storages once your new TH9 buildings are up to TH8 level parity, and once your xbows are at lv3.
