A few years ago there was a noticeable increase in the frequency of point updates at the expense of quality. In agile, testing either (a) relies heavily on automation or (b) only tests that particular story. In highly complex systems that's often not sufficient and rarely do security teams for example involve themselves on a per story basis.

Personally I think the industry as a whole needs to sit back and realise that Agile wasn't the panacea it was made out to be.
