To me, this layout was really lackluster.
Zero strategic implements, pretty lame rewards in my opinion (the credits from winning battles are probably better rewards) and since GA you do it 3 times in a row it becomes even more apparent how uninteresting this layout was.
With just 2 zones, all you do is just match your team's against each other and that's it. No deception, or hiding teams behind other teams. Just literally 6 fights.
If you have less offensive/defensive teams than your opponent, your only hope is for them to mess up.
If you have the advantage with a stronger roster, just pick the right counter and win. There's nothing else to it.
Please don't use the 2 zone horizontal layout again.
