I have not completed the MSQ yet, so I can't speak for all dungeons and trials. But the ones I did experience, both my husband and I had a blast with!
As Astrologian, I was forced to use skills I otherwise used in savage only. I actually felt busy, and I loved it! So personally, please keep up the challenge.

I can understand it if people are having issues with it, though, or would prefer a more relaxing/casual content.
So perhaps it would be possible to implement a system similar to solo instances, that let you lower the difficulty?
