Congratulations!

Coordination during battle can definitely make the difference between success and a party wipe. It can also open up the possibility of more challenging and exciting battles.

Between my two Linkshells, one does battles like random people thrown together with very little battle coordination. We tend to wipe more often.
(but I still love them)

My other Linkshell is much more coordinated, and they are a lot more successful with things like NM fights, dungeon runs, and getting high level gear.

The difference is quite clear. ^^
