The normal MSQ version of fights aren't intended to be difficult because many players are going through them for the sake of story and not a test of combat skill. To satisfy the latter, the former would be in danger of not being able to complete the content at all, and that's something that SE wants to avoid
Lower the maximum ilvl people can join at so the fight can play out a bit more naturally. - turning an MSQ boss into a brick wall that they have to do again..and again...and again...

There is a very good reason why the number of people who want to be closet masochist with min ilevel and no echo is very, VERY small

All you will do is put new players off.

MSQ is story content, meant to be easy, meant to be clearable, it isnt savage, or extreme, or uitimate.

NO.
