An idea for a WD visual indicator

One of the core tenets to the game, in dungeons, enemies, and skills, is to start with a foundation and slowly add things to expand/alter your understanding of them.

So far, aside from seeing the (de)buff on your character, there's no visual indicator to show how long until it wears off and you die. However, what could even be done to show that effectively to players, without having to introduce a new, wholly unique indicator for this one DRK skill? Is there something in the game already that can be repurposed to serve as an indicator for WD?

I argue there is, and it can be found in Ozma (Weeping City of Mhach) and Susano (normal and EX), amongst other fights. The spinning, countdown die overhead, I'd posit, could be used as the indicator for WD, and how long until it fades and, if not fully healed, the DRK will die.

The most important visual indicators that you need, as the ability is currently implemented, are:
1) How much time is left on WD
2) How much more healing is needed to cleanse WD

I think the best place for this would be on your HP party/target bar itself. One approach could be to overlay a grey/black bar on top of your HP bar when WD activates, representing the remaining amount of healing needed. As you heal the target in WD, the bar shrinks to show the HP bar underneath until it disappears. You could place a countdown timer either on the bar itself or next to it to show the time remaining.

That second piece of information, namely how much healing is still needed, would be really useful to know.
