State of Fifa Ultimate Team: Squad Battles

I play a mixture of Rivals, Champs, Squad battles, and online friendlies. The biggest frustration for me is Squad battles this year:

1. The game contanstantly crashes on me resulting to 0 points with a loss of 0-3 even though my team is winning by a fair margin. 
2. The Computer style of play is ridiculously toxic with consistent ball shielding and last millisecond passing.
3. The build up play is absolutely dry with multiple styles of attacking tactics. When it comes to telling your attackers for a run they either stop running and give up, or the AI defenders will track your runners with no room for error resulting to this option being useless.
4. There a blatant script moments where you press the opponents to a guaranteed tackle, then all of a sudden they do a 100 mile/hr pinged pass 40 yards away to the feet of their defender resulting to a foul. 
5. This goes for all game modes is the Heading Accuracy: the heading Accuracy is brutal this year no matter if you have precision header, areal fortress playstyles, with the players height being at a reasonably tall. Players stats for heading accuracy and jumping being in the 90's. 
6. What is the difference between World Class and Legendary when it comes to high chemistry and ratings? I play both and I dont see the difference between both. The difference between professional and world class is clear. 

There are other issues, but these are by far the most infuriating things about my experience with this game. I've been playing fifa since 2014 and im debating whether or not I should invest my time on the next year. I typically enjoyed squad battles after winding down after work and relax. But this year it just adds more stress.
