Yes, and also ranged combat.
However, since it is clear that it wasn’t a design idea to make every class EQUALLY good at both ranged and melee, this is where the imbalance comes from. You can’t have a range class be best at range combat and the EQUALLY good at melee as melee classes (who are not as good at ranged combat).
Again, you are comparing melee performance between a class that is specifically geared to stagger enemies in melee to a range specialist class. What options does Ogryn have in range combat with multiple shooter groups and/or snipers? Shield! That’s right, shield and nothing else. Sure, Ogryns also have some range options but what do you think would happen if instead of comparing melee, like we do in this thread, we start comparing range performance between Ogryn and SS. How would that comparison look?
I have a sense that you are too reliant on VT2 balance. VT2 has range combat as an afterthought so you have to give great melee options to all classes. In DT range is at least half of the combat and is especially important and difficult in Heresy+.
