They have added some new mechanics to each of the flashpoints as well. Definately a little bit harder now.
more like not being able to CC or stealth by certain things to be honest. Some bosses you could CC parts to make it easier but that is gone.
With group finder I've seen them more times than I can count, especially with healer/tank alt. Been sick and tired of Hammer Station for months, now I'm getting more of it, yay.
