It's just ridiculous how it is now. Sometimes you end up spending more time waiting for CDs than actually praticing on fights. Put together long fights (10min+), a lot of wipe mechanics, latency issues, etc, etc, and you have your stress. My personal guess is that SE thinks that it's "cool" to add those dumb dificulties to say the content has hard beaten, or challenging.
Or, they just want to dry your game time ($$).
