I finally finished my list
Top 25 best moments in this arc:
1. Natsu defeating infinite power Zeref with friendship punch
2. Erza vs Irene
3. Every Lucy fanservice moment which was like 70% of her scenes this arc
4. August's idiotic suicide
5. Dimaria having one of the most hax magics but primarily using it to strip people in the middle of a freaking war.
6. Makarov resurrection
7. Gajeel Fake death
8. Makarov's death against fodder
9. Juvia fake death
10. Brandish gets one shotted by Cana for comedy
11. Gray trying to commit suicide for like the fourth time and Natsu being the one to stop him again
12. Natsu learns about his past and that he is a demon but just says he's human rather than undergo any real character development
13. Everything about the time lapse and Anna’s return
14. Erza’s historia being defeated with just a look
15. Zeref x Mavis loli sex and her getting back together with him a chapter after he tried to destroy everything
16. Acno’s inability to easily destroy a ship that was one shotted by Wahl Icht. He chose to get embarrassed for 10 chapters rather then one shot that ship with a roar.
17. Elfman and Lisanna vs Ajeel
18. Irene being a dragon despite Acnologia not recognizing her as one in their first encounter
19. Jacob getting turned into a joke whose weakness is fanservice
20. Enchanted Neinhart getting one shotted
21. Gray and Lucy getting relegated to Natsu’s cheerleaders and book editors for the whole Natsu vs Zeref fight
22. Mirajane only getting fights against two swords and a guy who lost because her tits were exposed
23. Natsu vs Gray getting stopped prematurely and built up improperly
24. Return of Aquarius
25. Gods of Ishgar getting fodderized. If they were going to get beat so badly, I wish it was against one of the top spriggan.
Honorable mention: Almost every other moment in this fantastic arc.
And the mine are:
*Wendy now can resurrect the dead (Juvia)
*Brandish vs Lucy Epic Bath battle.
*An subordinate of Brandish, Marin, toying the main characters. 50 chapter later, Lucy alone can fight Brandish.
*Every guild of Fiore except FT is useless in the "war".
*Natsu four times "dying" in the arc -.-
*Zeref's face after the death of August and Irene and with nearly their entire amy defeated is like "meh, i don't care, i still can win"
*Brandish "I'm not your ally but i still will help you!"
*Ajeel wants go to war alone.
*Brandish has a island to their feets yet she can't do the same with a fucking town.
*Third Origin.
*Laxus is not sick anymore.
*Jacob wants solo Acnologia.
*Larcarde sex magic
*Gildarts is hungry.
*Erza, Mavis and Carla thinks that Nastu and Happy can solo Zeref and their entire army,
*Kagura-Erza Yuri Scene.
*Lucy "death" according crazy Natsu.
*Off-panel battles.
*Acnologia kills God Serena in one second yet he can't do the same to Jellal, Wendy or Erza.
