Put it this way, they fine tuned the normal mode for leveling, and hero mode for people who actually want challenge.
If you don't wanna do hero mode, there is always 4 man S3 raid and ein lacher for you MLGPRO players who think this game is too easy.
My experience over the last 2 weeks tells me half of the parties require hard carrying. There is at least one player in each of these parties that is just a dead weight, so you really have to try sometimes.
IMHO this game plays the best when someone has the skills to solo.
These are the kinds of people RISE is trying to retain, for them to invest more time into the game. It is not for the vets who can handle themselves at this lower content. Besides, once you reached endgame, did it really make sense that you can kill Neamhain within 15 minutes, but it would still take you 4 minutes to kill a dragon you fought when you were 100x weaker?
are people actually surprised old bosses turn into a joke over time
