how do i know when an attack is direct hit or crit?

Not 100% sure on that but I always prioritize on critical before direct hit. My cousin and I have been experimenting with it as sum and so far critical has paid off more. I could be wrong just our experience on it.

The reason SMNs take DH over Crit is because of the math. DH is mathematically better to take over Crit but SMN BiS is nearly even for Crit/DH.

DH>Crit>Det>SS is the optimal setup for SMN by the numbers.

As long as you've got a healthy amount of both Crit and DH you'll be fine either way.
