Blocking and swiping for balance

Like the horrendous and blatant pass interference, blocking has always been a major issue that needs to be addressed. Their are 22 players on the field at the same time all of the time and its 11 players on the field for each team at the same time all of the time so why is it that no matter what, our blockers are always double teaming defenders even when the play is designed specifically for them to block a defender individually and when there's no need for it? And to make matters worse, they, quite often, don't even attempt to block anyone, not a chuck, push, bump or nothing and they always release their blocks extremely early before you even get to them and run off down the field where there is no one to block and like they have the ball only to turn back around looking for someone to block. It just seems like we're being sabotaged at every corner, all the time, all the way around the board. Can y'all please fix this. 

And with swiping for balance, I can honestly say that it hasn't worked for me almost at all since it was added. If I've tried to swipe 100 times, it worked 4, maybe, 5 times. And it's the same thing for trucking. I don't even bother trying to truck anymore and haven't in a month or so.
