It's true that farming at TH10 is harder than TH9 but it definitely has gotten a lot easier. At TH10, you should mostly be farming TH10 and TH9s.
Because you are farming against bases that's stacked with a lot of harder defenses, you would have to adjust your army composition accordingly. For example substitute goblins for other units such as barbs/giants/archers or find a totally different farming style which I did.
I suggest you make your camp upgrade your first priority. TH10 only offers camp space as offensive upgrades unless you count wall breaker, golems,pekka and dragons. Once you get to 240 camp space it gets a lot easier.
I am currently parked anywhere between 1900-2200 to farm. I suspect you can go as low as 1800 and still do well.
Hope this help some.
