I'm here to say that I love the current difficulty of the dungeons, trials and raids. For once in many expansions, I don't feel like I'm falling asleep doing them. I'm having a blast with them. I like seeing the occasional wipes.
Players need to learn that it's fine to fail things. Guess what, the next day your brain processed things so that things go a bit more smooth the next time.

Stop wanting everything to be a walk in the park. I'm all for easy content when it's early in the game. But we are how many expansions past ARR? It's time to actually put all the things you learned over those dungeons/trials/raids into actual practice.
Besides, it's still easy to get carried by others. Unless both healers keep dieing at the same time and you don't have a rdm in your party.
