[discussion] Why do people say Lucy is the MC/protagonist

I don't get when people think Lucy is the MC/protagonist and not Natsu, or say that she's more important to the plot. Seriously when?

Galuna Island starts with Natsu wanting to do an illegal S Class mission and the climax ends with him stopping Gray from using Iced Shell and destroying Deliora setting him on the path to heal from his past while Lucy never even saw Gray try to use it.

Phantom Lord which is suppose to be Lucy's arc has her greatest contribulation be feeding Natsu fire while Natsu took out the Jupiter cannon, Totomaru and then Gajeel.

Tower of Heaven has Natsu be the one to save Erza and fight Jellal, making her see that you don't die for your friends, you live for them, while again Lucy never even got to see Jellal.

Battle of Fairy Tail has Natsu be the one to break Erza out of stone and beat sense into Laxus, while Lucy did fight Bickslow an dgive the whole speech which was nice, didn't have as much screen time as Natsu's actions.

Oracion Seis is resolved with Natsu overcoming his grudge with Jellal and accepting his help to bea Zero.

Edolas has Natsu be the one to destroy the Dorma Anim and give the goodbye Ceremony to Mystogan while also making him the hero and leader of Edolas.

Tenrou Island has Natsu have his fight with Gildarts, meet the main villian of the series Zeref, beat Zanrow, do most of the work beating Kain, and take the lead against Hades and even Acnologia.

I think we all know how dirty Lucy was done during the Grand Magic Games, though Lucy did close the Eclipse Gate but Natsu was also the one to destroy it and send the dragons back.

Tartaros had Lucy save the whole guild which a really cool moment don't get me wrong, but not the climax, that goes to FACE, which the Parent Dragons destroyed, and Mard Geer who Gray and Natsu fought, and the big emotional moment at the end of the action was Igneel's death which was more lasting than Aquarius's sacrifice cause Lucy had to immediately go into battle, not really being allowed to cry and not many others really acknowledged it, while Igneel had a Eulogy from Metalicana and Gajeel seeing Natsu cry, and Natsu going on his training journey cause of it.

Alvarez, it's about Zeref and Acnologia who both have way more of a connection to Natsu than Lucy and Natsu played the biggest role in beating Zeref.

Sure, we may follow Lucy more during downtime, but when the plot actually kicks in it goes straight to Natsu.
