Its not because wendy and lucy "can't" fight .but they are in a hurry to stop FACE ,so they don't have the time for a fight
Isn't that what everyone wants ? Natsu doesn't fight the strongest etc..
Anyway i wont say its boring but i think it went fast with nothing interesting happening (except that gray is "silver's" )
Natsu is supposed to fight the strongest ones. He fought Jellal, fought Laxus, fought Gildarts, he fights guild masters... he's set up to fight Zeref... he's supposed to be taking out legitimate opponents, Natsu deserves more than some Ditto/Majin Buu fodder rip off.
Also, Wendy has offensive capabilities but she used none of them to protect herself while running towards FACE . She could have used her dragon's breath to repel attacks or to clear enemies out of her way, but no, she was instead saved by Grey and Natsu. Like I said, wasted potential.
Literally, all they did was drop a smoke bomb and run. Not very magical....
And the whole Face thing... if that weapon actually goes off and everyone's magic gets taken away, do you know how boring this manga will become? They'll have to stick to Erza ecchi scenes just to keep it remotely interesting
