Rogal Dorn - meltas or stubbers

What do you choose and why?

Personally I’ve tended to keep my Dorn at the back or a flank targeting mainly opportunity targets as it’s quite good at anti tank with ap support but really excels at light vehicles and heavy infantry. Overkill light infantry but gets the job done.

My Demo tanks get up close and do most of the heavy lifting.

So I give my Dorn stubbers just for distance, chip damage and volume of fire.

I think I’ll be sticking with combined detachment and upgrading my Dorn to a TC supported with an exterminator.

Just wondering if to change up my style and loadout. Happy for ideas thanks.
