I get the idea behind giving the Heavy the HBR. It gives you more mobility but it is way outperformed by the heavy bolter. Making it feel like a poor choice. You also lose out on heavy stance. A core feature of the heavy. It feels out of place even if you give Heavy stance to the HBR. You might as well be using the heavy bolter at that point. But the test server just launched and i was looking at the stuff in the duelling arena. So maybe i am missing something or am wrong.
