I'll just parrot what so many are saying with the hope that devs are listening.
The generic bosses are too hard (or too numerous - probably both).
This isn't fun.
I too, last night (someone mentioned the difficulty of Devoured Earth missions with the many many lesser devoured running around) I was in a 3 person mish against Devoured Earth and died 4, yes FOUR times. I won't go into details because everyone is gruesomely familiar with how these scenarios are playing out.
It wasn't fun.
