Kowing how to do it an executing that are different things. It is no secret that this encounter was very unforgiving for melee groups before the patch, if it was not so it would not be tuned the way it currently is. Bioware obviously doesn't agree that both ranged and melee dps group experience the same level of difficulty in that flashpoint. All this talk uttered by people is nothing short of showing off (I am pro) attitude.
I am Infiltration shadow, there is no showing off with that class. That is one of my reasons for thinking LI HM has always been easy, if I can do it with that spec and my lack of skill everyone should be able to do it. I do however know my abilities.
