A visual display of Aetherflow amounts is a crutch for new scholars and is something you should very rapidly be transitioning out of.

You should be mentally tracking your remaining stacks as it coincides with enemy mechanics. Generally, you should be using 1 Lustrate every 20 seconds to maximize your Aetherflow MP efficiency.

Relying on visual feedback for Aetherflow distracts you from what you should be focusing on and keeping in mind, which are predictable mechanics and unexpected events (critical damage, party members stepping into AoE cleaves, etc).

If anything, a visual display harms, rather than helps, new scholars. This shouldn't be implemented.
