Ran a 16 man story mode EV for achivements only and it didn't award us for council or the pylon fight.
These achievements are so buggy I'm not sure why you guys would implement them into the game. What sense does it make that NONE of the previous hard modes show up for kills. You guys are on crack if you think the players want to go back and kill bosses on lvl 50 hard modes 25 times when we've already done many more than that.
