Communication is key
With addition of level 55 I assume in 50 hardmose a skipping is less desirable
Now it's kill everything for exp and gear
Some level 55's want skip stuff but that is just not cool, got to do for the group
Quite the opposite, the faster you get through the more flashpoints you can complete in a given timeframe and most of the experience comes from completing certain goals - this does include the bonus boss and finishing the dungeon. But anything that isn't vital to those two things can be skipped easily.
