Most of you might be facing loot problems after upgrading to TH12. After moving up and down in different leagues I found the best trophy range for Town Hall level 12.
I find a lot of dead bases in this trophy range. Try to maintain your trophies between 2200-2400 and I can assure you that you will find some good loot here. Crystal league is always good for farming. You won't lose much loot here because most of the attackers in this league use to attack dead bases and avoid active bases.
At TH12 you can farm in champion league too. You won't find dead bases here, but the loot bonus is enough to fill your storages in a few hours. You might be thinking why should you farm between 3200-3400? The answer is that the bases here are easier to destroy. You can easily get 70% of the base by using LavaLoon. Champion league II is also good to farm loot but I prefer 3200-3400 range.
That's all I have today. I hope you enjoyed today's guide. Share your views and opinions in comments. Clash On!
