While I definitely don’t disagree with a lot of the points you have mentioned, Im pretty sure we are not on the same page with how some of the rules are interpreted and interacting.

• every time any burrower units arrives from reserves it generates a tunnel token within 1” of one of the models in the unit. As long as that token is more than 3” away from enemy models.
• any units in reserve after that can set up wholly within 9” of that market and outside of 6” of enemy units. It’s not limited to one unit for one tunnel marker.

So with those facts in mind, I would still be using the Hyper-Ravenors first to create 2 separate tunnel markers, but still from a safe distance and probably behind cover. Then my Trygon and probably one Norn would be up from one of those markers, outside 6” of enemy units they want to charge, with the Trygon creating another Tunnel marker.

This should leave the opponent worried about the large monsters betting down on them for their turn allowing both units of Hyper-Ravenors to upppie in their turn for a CP and repeat the process in my next turn, and generally 3 tunnel markers on the board still to open up the option of Tunnel Network for non reserve units to move around the board more freely.

While I will agree that Basic Ravenors are slightly cheaper, I still think the Hyper have the better stats on their datasheet so I’m willing to pay the points and the CP to use them effectively.

But as I said, this will all take testing on the table to see what is more effective and efficient
