Here's where I stand at the moment: assuming that leaving No2 at CLB was a major factor, and that this is 'eliminated' by repetition of 'warnings', I would like to see the following recs out of this:
1) Planned landings on 'slippery' runways barred if T/Rs are not 100% (common practice in my experience)
2) A realistic MEL addition for LDR with one or more u/s, which varies with runway condition (common practice in my experience)
3) A 'standard' (international) downgrading of a runway that has been re-surfaced but not grooved to 'slippery when wet' - enough recent 'evidence' that this is so
4) an increased CVR time made urgent rather than 'convenient'
We can forget all the mumbo-jumbo of logic circuits/sensors etc and with a re-empahsis on 'basic' flying skills plus the above I would hope we will have learnt sufficiently from this tragic accident.
