We are not moaning about frequency of switching, we are complaining about WHO the system switches to when the button is pressed.
For Example:
I am RB tracking back covering the opponent's stronger side. He cuts in (as expected) and delivers a lobbed pass with his weaker foot. The ball goes over the head of CB2 and lands behind CB1, who is about 1 yard in front of it.
I press the switch button.
Instead of switching me to CB1 who has the best chance of getting the ball (or making a tackle) I am switched to CB2 who has no chance of getting there in time.
To compound matters, CB1 (who is under AI control) makes no attempt whatsoever to close down the ball. I still have a split second before their CF gets his first touch so I press L1 again hoping that it would correctly choose CB1. It instead reverts me back to the RB, who is still on the flank. Easy tap in goal.
The switching system is a disaster. Hopefully the illustration helps convey our frustrations
