Yes. I said that many times. It's quite obvious that END plot didn't add anything to the plot because it got killed indirectly.
Before Alverz:
-E.N.D. is the master demon and the founder of tartarous.
-END is stronger than Igneel (Atlas flames)
-Acnologia possibly knows END and feared him.
-All the dragons including Acnologia appeared to stop his rebirth.
In Alverz
-END is innocent and brought back to life as as 5 years demon.
-Igneel could have killed Natsu but he didn't because he love him. *Atlas flame words became a joke + giving us False hype
-Acnologia didn't meet END before because he traveled to the future, No reason to fear him.
-Mard geer was just using his name to gather the demons.
It would have been better if Natsu and Lucy were involved only in END plot. Mashima and most the fans would not have any problem if Lucy is the one who defeated END, Simply by creating the demon slaying magic out of no where and fueling it's wielder with false revenge it created a darker tone as the MC must fight his friend to death and we got a sample of it in the current arc. It also created toxic atmosphere between fans. I think he realized the out come of the real END plot that he forced didn't fit FT theme.
