So for some reason in Attack Phase, i cant seem to switch out any of my monsters. Since i couldnt switch, i figured id just use the first three they gave me. Then the second time i went to attack it was the same thing. Plus its going from the top of my list, so all my ranked monsters are being used first

Same here, and also some of my team members complained. This must be a bug

Yeah i heard back from team members about it too. Definitely a bug

This has completely ruined this Battlegrounds. My default team is worthless.
