I disagree, here's why. All of the achievements for the emblem are PvE-based except win 100 Crucible matches, a feat than anyone who plays regularly can achieve thanks to the fact it's any Crucible game type, so people aren't forced into one type of play (like Elimination) that they hate. The hardest achievement on there is Skolas, but that's about on par with having beaten CE Hard back when the level cap was 32. The only difference is you have 3 people instead of 6, and it's a different type of activity rather than a raid. Not impossible in the least. Whereas in Trials, you are facing real people and not an AI, so it's much harder. All Skolas requires is a strategy and the proper weapons. Trials requires luck, skill in PvP, and team coordination that some people can't achieve.
