I used to play DDO when it was somewhat hard. It never was really hard to begin with, save for a few quest. I remember Elite Dreaming Dark was rather tough a couple years ago. Crucible as well was quite cool. But most of the content wasn't particularly hard.
It's just totally out of control now. Nothing is challenging. No reason to play... You get bored TRing and farming loot that's going to be worthless the update after. Or duped.
