In my opinion, the hardest part of ANY raid is finding a group of 6 competent people that just understand the ways of Destiny and playing raids. I think there should be a challenge mode that's harder than what we have now. I was hoping the challenge modes were going to have modifiers when they first came out. Could you imagine doing Crotas End with Arc burn on?! Lol, it would be a pain but the victory would feel even better. Plus it would add another use to things like the Adept weapons, where they really only shine in strikes and nightfall if there's a burn (oh and CoE if you do that). Who hopes that there is some legendary hard mode for raids in D2? P.S. The only thing that sucks about having super hard modes is the people who are able to beat them expect to get better loot than normal, but then it creates that gap with the casual players who can't complete it and say it's not fair for them that they can't gain access to the best weapons. What do other people think?
