I feel the same way.. been playing this game since 2005 and this update just ruined it.. my GK would make at least one blunder per game, my defence is useless, went from being the best defence in the league to conceding 14 goals in 4 matches.. I'm a defensive-minded player and this ruins it for me. And just like you, I spent sooo much time trying to find the perfect tactic for me, this one worked like a charm and now poof, it's gone. Ruined it.
