This probably should have stopped you from posting any of that. As someone who played both casters at top levels of content in 2.0, I found SMN far easier to "faceroll" than BLM. If you mess up one thing as a SMN, who cares? You still have lots of other spells, pets, and abilities keeping your DPS up there. Fix it and keep going. One mistake as a BLM and you'd watch your DPS tank. BLM difficulty wasn't in the rotation, it was in the management of movement and stances, something SMN didn't need to worry about nearly as much. If you just did the BLM rotation without perfecting the movement and stances, you were probably a pretty terrible BLM.
All that aside, BLM is now high risk for an average reward. Perfect Enochian rotations will still put us in the middle of the pack of other perfectly executed DPS rotations. However, there is extremely high risk for that average reward. The QoL changes HaroldSaxon proposed above are what I believe is needed to fix that.
Edit: To be clear, I'm advocating for reducing the risk, not increasing the reward.
