Do not maximize the level of your shinsu link for all five (5) spots.
Leveling up the shinsu link has a great impact on the character's attack and other status especially when shinsu link reached a limit break.
1 or 2 shinsu link spot that will be designated for the carry character, should be above the level of the other 3 or 4. In this way, the designated carry character shall receive the priority buff from the support allies that gives priority buff to allies with the highest attack.
This strategy will surely help you clear stages and even in arena.
Example: Evan skill, Adam's Glove prioritize giving the buff to an ally with the highest attack.
