I agree with you, the game is great and has its potential, but... Why there`s so much negativity? I think that people at first were just happy, seeing the game, trying it out, expecting some stuff to be tweaked for full version, but when it came, more and more weird stuff started to show up, there were no transfers made and everyone had to wait a month for fully updated game. The update comes out on thursday, its still not there, but at least few days left. I know, its strange, but people who are used to Konami and PES, knows there will be lots of strange stuff, but the gameplay itself usually would keep a balance. At the moment, there are lots of people who are just stuck, the same as me. Due to so serious goalkeeper/AI/defence/easy scoring problems, people just dont want to play it anymore. The game looks nice, nice player models, nice movement, but because of above mentioned problems, the game cant last a full year. I dont think many expected this, but as it turned out to be, there are even more flaws than in PES 15, which was at least a bit stable in some way.
Im not saying everyone dislikes it and turns away to FIFA or to nothing, there are lots of who enjoy it as well, but I can see a tendencie, which is pretty much valid, reasonable, because I can even relate myself to that. Usually I let all the negativity go past, since you cant be good to all and fulfill everyones needs, but now, I think, there are some basic problems that have to be solved in order to make this game more stable and lasting.
