As each new chapter is released, and Natsu and co. breeze through these fights, I worry more and more that they are gonna breeze through the tournament as well. Honestly, and this may be a good thing, but I'll be truly shocked the next time we see someone get the best of a FT member, especially one of the core characters.
I get the feeling that EVERYONE is now fodder for the plot, with the main villain (maybe Zeref, maybe Aknologia, maybe someone new)and possibly the dragons, being the only real challenge for Fairy Tail.
