DR with 8 people is quite doable when everyone uses pure essence and proper lost actions.
The problem is that the Echo doesn't scale enough at all when you go in as a group of under 8.
In fact the echo feels almost the same no matter you are in a group of 2 or 8. (I haven't tried solo yet but I don't expect it to be too different)

A lot of newbies not understanding the dungeon just go in to have a random match and they rage quit after seeing how tough the first boss is.
I've heard this a lot and actually seen it myself.
I mean if it were still a brand-new content, of course it shouldn't be made too easy. But at this point it's almost a dead town already.
Why not just make it easy for everyone like how the past relic weapons are all easily soloable? (except BA obviously)
