Yes, Your combat table will look something like this:
Miss: 10%
Dodge: 15%
Parry: 15%
Block: 50%
Crush: 12.4%
Hit: 0%
This means that every time you take damage it will be like one of the following:
Gruul hits you for 4000 (400 blocked)
or
Gruul hits you for 6800 (crushing)
You will never see: (Gruul hits you for 4400.)
I think where it gets confusing is when we use "getting hit" technically to mean "taking a non-crit, non-crush, unblocked melee attack,) as opposed to the more generic "taking damage." Not every swing that damages you will be a crushing blow, just the ones you don't block.
