Squad battles sudden increase in difficulty...

Last two weeks I have noticed that squad battles have become way harder than before.

I can easily destroy great teams in World Class difficulty, 6-0, 8-0, etc. When I play those same teams in Legendary, it's way closer. It's almost a toss up. Sometimes I win, other times I lose but games are way closer.

Now, for points, I choose World Class difficulty on the tougher teams in the last round of Squad Battles. But seems like they increase to Legendary. Games are way tougher... 

Anyone else run into this? Kind of annoying that EA would do this to prevent people from making Elite 1 in Squad Battles.
