We cleared 3 Hardmodes with some pvp gear and corellia gear, if u have such gear its close with the enrage timer but possible if the players can play their class and u know what to do during the fight. as of now, with a lot of purple gear, most of the hard modes are pretty easy, but still very entertaining, especially when you try a new one. So yes, the flashpoints in hard mode are hard, but very possible if the players know their class/spec and the fight.
