Good for you. I havent been able to find a guild that does a lot of HM Flashpoints.
Ive tried 2. On Black Talon we got wiped on the first boss and on the other one our healer DC'd so we had to quit.
So for me the only way I can get endgame gear is by doing the armaments quest over and over. Once I have my champ gear Im done with this game.
