If this is so, then why is there need for training above knowledge of the system and aircraft limitations without MCAS.

IMO the story is something like Catch 22:
- MCAS is needed to meet certification requirements, but it will rarely be activated, and if there is AOA disagree then MCAS will be inhibited, but the conditions under which AOA disagree occurs are only rarely encountered in the normal flight envelope.
- Boeing must test all of this, and the FAA must verify all of this, and the airlines should understand all of this, and pilots should have some knowledge and awareness of this.
- It is not necessary for each pilot to train for this on a simulator, since it is extremely unlikely to activate, and the average pilot would not actually notice the difference when MCAS activated, and would not have to take any action other than the normal control inputs.
Unless it fails in some way, which is still the elephant in the room...
