Farming ISO

So I am sure this has been discussed over and over again, but please excuse if I ask again… 
What‘s your favorite place to farm ISO?
Now I know, best way to farm is duping 4* champs… But if you don‘t have the shards at hand, what do you do?
Personally I have just recently realized that there are a lot of T5B ISO in the monthly event quest, so I farm ISO in chapter 1.2 of normal difficulty… The path with one 3* chest and one 4* chest grants a total of 7 T5B ISO bricks. 21k basic iso for 18 energy. Not bad.
Has anyone found a better spot to farm ISO?
And if what I‘ve just realized is common knowledge: Is it every month that there is a short path with 21k ISO?
