We miss a visual Buff feedback

The title explains perfectly what I mean I suppose.
Ok we can’t have parses in game and I m ok with it but what about getting a visual effect for buff indicating how much that player or the team is buffed ?
I think it would be much pleasant for everyone like me who love playing and buff people with job like dancer, Astrologian, bard, etc..to have something like this to show us and other party member how much we are doing our part.

Maybe an indicator next to the party member name who gets:
Green for low buffs
Yellow for medium level buff
Red with flame when he/she is getting high level buff

These kind of feedback would also help the buffed player to understand when they re buffed and when they need to burst if they can

Um... what? You can already tell when you have a buff. If you want the icons to be bigger, just make them bigger.
