I noticed that the following attribute heroic achievements were bugged. A couple of these are for all classes. 

1. Unburdended (actually shows 70/50)

2. Only War

3. Perfect Record (have now completed two without dying or failing any stage)

4. Scourged by war (the warp count on the other one is going up, this one bar doesn't budge)

I'll try to do the ten with only powers next to see if that is bugged or not...should crank the warp heat that way too..lol

On a side note, with the barrels and the stationary turrets being untargetable it is really going to do a number on a couple of assassin heroic attribute unlocks.
