I just wanted to tell my fellow RLs about a new useful addon made from one my my officers: Kimbra.
It's called Skada - Lightwell, and adds Lightwell usage (useful usage and USELESS usages, when you are already at full health) to skada, so you can track and check who is slacking and not clicking the lightwell during the various boss encounters.

Kimbra will soon also add the "Effective Self-healing done thru Lightwell" tracking too, so you can check who are the best ones to use the lightwell when it's needed and the worst ones that never click it or click it when it's totally wasted ;-)
Currently it tracks:
Useful usage count per raid member: when a raid member clicks on it and its not at full health
Useless usage count per raid member: when a raid member clicks on it and its at full health already
