This stuff aged poorly. Clunky menus, terrible (truly terrible) AI, confusing class system (they did SO WELL in FFTA) and the story is indeed old by now. I was searching for another fft games aside from ffta and ffta2, but this one got me bored in like maybe 2 or 3 hours. Terrible.
The game is in a terrible state. Both the matchmaking system and the community are suffering from horrible decisions.
If you're playing this alone, either make friends quick or just play this like a casual Candy Crush game. There is nothing for you. Community is toxic and not helpful at all. Since OW release a bunch of better teamplay games have been released, throwing this one out of the window. The balancing aspect in the game is far gone, replaced by the "everyone is a DPS" thing to shorten queues. The game is also struggling to keep you entertained with almost no new content and generally low replayability aside the same matches on your rank over and over. Play it with someone and try to have fun. Not recommended.
