The MSQ, like you mentioned, it was intended to be filler and idk why some people had such high expectations for it. I'd even say that is a pretty cool story for a filler and Zero is an interesting character.

Raid storyline, feels weaker than ShB, and at the same level of HW and SB, but that's probably because Eden really felt like part of the MSQ due to its importance.

Honestly, the point that I put as outright bad for EW (and ShB partially) is Job design, which of course involves the infamous 2min meta burst for all the points stated in the OP, and honestly? I can't see the team managing to deliver an exciting job design as long as this cursed thing lives. So and so that my big expectation (unrealistic for some) for 7.0 is just one job but the resources that a second job would take being used to overhaul the 2min meta.
