A330 DECs will help senior 330/340 Captains get released to the A380.
Senior F/Os on the 330/340 are going to the 380 anyway and therefore DEC's are
not going to affect them.
I don't think this round of DEC intakes for the 330 is going to be so disruptive to 330 F/Os.
They have just reduced the the command requirement on the 380 for F/Os from 2500 hrs to 2000 hrs.
