You said pretty much everything! GMG was the "prelude to the chaos". The point I was lost all the hope was Tartaros arc, and I almost gained it back at the beginning of Alvarez, seeing how Brandish amazed Erza and Natsu, how Makarov trembled before August and Erza vs Ajeel seemed quite okay to me. But then, everything fell apart again and now I'm just sad because FT had everything to be fantastic. And yet, here we are, 10 chapters from the end, talking about how shitty it became.
