WHM main here.

I did not play much in Stormblood and used Trusts for all of the MSQ in Shadowbringers but have done roulettes, etc since.

When the tank does big pulls I can definitely feel they are taking more damage than they did in ARR or HW. It definitely has taken time for me to adjust.

The most difficult thing is getting used to each individual tank though. They all seem to have a different idea of when to use their cool downs.
