So... This is the "improved encounter design"?

I felt like on normal they took so long it made me not want to do them again.

They get faster with gear. Plus, the people who took ages were probably still learning mechanics and will be better at them now. The timeframe now is the same as any previous raids we've had, but eventually it will be as quick as P1-P4 by the end of the expansion.
