I will say it again, mDPS was easy before or after 1.4 provide the player knew his/her abilities. Any fight in the game can be done with either mDPS or rDPS, just as easily if both groups know their abilities and knows living average DPS is better than the greatest dead DPS.
Knowing 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.
