Hi Tourist,
They would rather you just did what the ECAM says, in effect performing as the avatar for the computer.
I think even Airbus recognises that ECAM doesn't provide all the answers. It's a pity crews like yourself feel you can't use your technical knowledge and experience to anticipate what ECAM will tell you to do later. e.g. Cabin ALT shows rate of climb & outflow valve fully closed = Suspected door seal leak. You can't prevent cabin ALT from climbing - but no ECAM yet.
Do you sit there and wait for ECAM "EXCESS CAB ALT" to tell you what to do or do you anticipate the problem and initiate a precautionary descent?
