MD83FO:
Not much is said about the performance of engine thrust from what i read on the report, if thrust reaction is fast enough this event shouldn't occur,
Fair point, notwithstanding, the crew should have been aware that thrust would sometimes be delayed and go straight to Airbus golden rule number 4 if necessary.
The thrust is sometimes slow as you say and perhaps this played a part, as fast as it might be though, no aircraft FBW or otherwise can defy the laws of physics.
