I like what you said, but having them in a two triangles all the time wasn't my favorite part. Almost like it forced you to go with three physical attacker and two mages or three mages and two attacks.
FFIV would've been better off with four member parties.
Five member parties are good but the row system FFIV used wasn't.
Five member parties and the FFIV row system were good. It should've been in other FFs though.
