I'd say from my experience an easy mode rather hurts than helps anyone (especially the dedicated players that go for the hardest modes). Why is that so? Well, the thing is I've played various games that had the exact same approach to hard content with different stages that had different mechanics and scaling etc. - and boy did you have a hard time when trying to go for the upper third of the difficulty scale.That was almost exclusively caused by people that cleared a lower level once or maybe twice, thought "eh that aint as bad now innit" to themselves and went straight for the hardest difficulty. Often times they'd just plain ignore new or re-spec'd mechanics and try to excuse themselves "because in normal mode it was like thisnthat". Even when we explained it to them what feels like a billion times they were unable and/or unwilling to adapt and caused wipe over wipe over wipe. (Gotta add that the specific game I am talking about here has no actual way of kicking a player and looking for a new one during a dungeon or raid so you are basically stuck with those lazy arses once you're inside - GW2 at least has that function)
