Oh I Used to complain a lot about the gameplay, but that was usually more in terms of ping, pay to win teams in lower leagues, and general matchmaking. I have ever never really bought in to the whole "the game is rigged" idea. Mostly because this is a division based game and people seem to struggle with the idea of "the more you win, the higher you go in divs/comps, the better the opponents get."
I also do feel that there is often a noticeable difference from game to game in terms of how responsive my players feel but as far as that changing from the first half to the second half, no, I don't agree with that. Even IF I thought there was some "scripting" going on I would also assume that it works against me no more then it would work for me, why assume that it's always against you?
