There have been some rare flat tracks but more often than not it's been a dustbowl.
Just look at the previous series vs Eng in India...1st test was a flat track where India lost and then had to turn back to preparing minefields to win the series.
Even Joe Root got a 5-fer there
I gave you an example of the entire series which was a road. Look up the 2016 Eng-Ind series with 5 tests. All 5 tests were total road. Yes, India won 0-4.
India even put the seamer-friendly track in one test against Aus in one series and won the test.
Yes, Indians tracks are sharp turners most of the time. That's given, but I was pointing out that they have a bowling unit to do well and win in different conditions. Pakistan's resources are a lot more limited and I think the best option is to have turning tracks. It's the best option even for Indians, but they could win in some other tracks as well even though it's harder for them.
To put it in perspective,
Since 2016, here are their pacers figure at home,
Yadav 75 wickets - avg 25
Shami 56 wickets - avg 22
Sharma 41 wickets - avg 26
Kumar 18 wickets - avg 20
Bumrah 14 wickets - avg 15
So pacers have taken 200+ wickets with an average of the lower 20s. So any claim that Indians have dominated at home in the last 6-7 years only due to turning tracks misses the point totally. Turning tracks definitely helped them, but they had ATG bowling unit for home conditions in the last 6-7 years.
