One of the things i read in the letter's summary is that many people are complaining about the difficulty of the HM dungeons. But I don't think the solution is to nerf it altogether. The dungeons definitely ARE challenging, but I believe that its because people go in there with inadequate gear. So if you increase the item level, players will be able to completely enjoy the dungeon, and still have room to make an error here or there. The dungeons are truly fun, and i feel part of that stems from the difficulty behind it.

it would also help if there was some sort of in-game help feature. like something that gives you pre battle hints on what the boss's attack style is and/or other things to look out for. not everyone bothers to look up youtube videos. so make it easier for those that don't.
