Squad Battles Gameplay

Ever since the ‘matchmaking’ update my squad battles gameplay has been impossible. 

Previously if I played say 90 rated team on legendary I should win narrowly or perhaps lose narrowly. 

Now, as an example I played an 88 team. Could hardly touch the ball and was 5-0 down after 30 mins. First time I’ve ever quit a SB game. 

What’s going on?

My match reports say great connection so the resident troll can stay away from this thread.
