It's astonishing that even a large number of 25's don't seem to know what you need to do to turn events heroic. For example you are about to place the 6th arc charge and some bozo goes and finishes off the first walker before the event turns heroic. Or in glimmer drilling you are about to destroy the third drill and someone goes and kills 4 of 4. Surely everyone knows what's required to make them go heroic? Or is there some reason why some folks aren't fussed about making them heroic? EDIT: so just to update the consensus seems to be that apart from deliberate trolls it's basically because most think rewards are no better for Normal or Heroic. I have to say that's not my experience. I know it's usually the standard two tokens and a blue but I've had legendaries and just 2 or 3 times, an exotic and I'm pretty sure those better rewards were always from Heroic. Another point made by a lot of people below is that it's not just about the chest. It's also the XP. Now maybe Eververse bright engrams aren't THE most important thing in the world but from time to time I've got a helpful ghost that way. It's perhaps more important for the clan XP after the Tuesday reset when you are just grinding to get Hawthorne's reward. Oh and for the replies that describe me as "kid" - thanks, I am 55 but it helps to recapture my youth!
