As I explained, you're currently penalised for having perfect balance, a very common scenario when the goal is to balance your mana levels.
This is very disruptive to your rotation and flow of battle, when you'd like to jump into your melee rotation you'll find yourself discouraged at the risk of losing DPS, so you have to cast another spell before you burst, which delays your burst and again reduces your average DPS.

There's no reason to penalise having a perfect balance. It wouldn't lead you to ignoring the balance gauge altogether, because you'd still need to know if one was higher than the other, or if they were equal, to know which finisher you'll need and which follow up spell will proc.

As it stands, you're paying too much attention to the balance gauge, because you're not just thinking "which one is lowest" you're thinking "which one is lowest, and which spell will not put me in perfect balance, I can either add 9 or 11 and need to ensure the diference between levels isn't exactly 9 or 11" you're forced to do constant arithmetic, which is distracting.

Having a viable option for either scenario doesn't remove any difficulty or result in less attention being required, too much reduction in attention rather, because which of the three options you find yourself using still affects how your rotation progresses.
