So think about this a little. There are a lot of guilds who are only beginning the progression to TFB HM so it'll be only a very few percentage of players who will get the 33 Commendations. You don't get 28 Comms in EC HM anymore unless I'm mistaken, you get only 20 (chests have been removed). This is equal to weeks of grinding just for an implant piece. Something is wrong with that.
If some1 is not doing TfB HM, he should not be working on Hazmat implants, Black Hole ones are much more cheaper, almost as efficient (even more depending on gear setup) and absolutely enough for smashing EC HM.
