Why do you hate it? Personally, I loved it. It was easily my favorite Tales of game.
This is about Xillia 2
It features a silent protagonist with little no actually roleplaying.
Lazy world building (Hope you remember Xillia, because we're only going to explain what's happened since then!)
Debt mechanic (15 million gald! Annoying debt collector calling you every other time you pick up money! Repeating the same 5 lines of dialogue ad nauseum!)
Job system (To get money to pay off your debt by killing X amout of enemy Y!)
Endless recycling from Xillia (hey, it's that one boss again for no adequate reason! And the same areas/dungeons! And I hope you liked the party members from the first game, because that's all you're getting!)
Fast, unexplained plot (Weird shit keeps happening at a breakneck pace, and nobody seems to care!)
Token Loli (Extra annoying tsundere edition!)
