Lol is it because u don't know how to platform or is it because the other people in the PE arnt even trying to make it heroic so u never have enough time to make it heroic?
well, I noticed that I never had to do it before until I finished it and it didn't go heroic.. so I decided to help out people who would do it.. and maybe 6/10 times, we run out of time destroying the diamond things..
Yeah it's pretty easy, make sure you have an auto rifle if you are alone though because they disappear quickly and then you fall lol. I recommend two people to turn it heroic.
