Game Version:

TBC Classic 2.5.2.41446

Suggestion:

I'd like a function to show large debuffs above the enemy nameplate while at the same time keeping the looks of Blizzards' default nameplates.

My Attempts to tackle the issue:

I tried to look for other addons to achieve this, eg BigDebuff but the latter was missing some relevant Debuff spells. I tried configuring Platers' own plates for a more default-like look too, but would be happier with the original.

All visualization / styles can be changed via configuration and modding. Iirc there is a default style profile on wago.io already.

Plater either has a module enabled or disabled, there won't be anything in between.
