It’s a relatively simple question, I was trying to leveling the target ark by using 2 max lv (which means lv 99 with a full exp bar sparkling) aoe ark, but I am not quite sure if they two still shares exp, is this supposed to be the most efficient way?
The exp gets shared across the three arks so yes it is wasted on the maxed out arks but on the other hand having two max level arks in the battle increases the amount of experience you earn overall so the lower level ark gets more. Also the higher level arks are less likely to get killed so the experience is less likely to be shared across 4+ monsters
There is a thread called “Leveling Made Easy” in the same sub group as this.

Using that method your able to level two arks at once instead if just one.
