I think it’s less to do with being told that they did something and more feeling like they did something.
I also feel like thematically the class has been lacking; Court Wizard is a glorified guard right now. Ice ward essentially does the same thing a Mercenary does minus the perks of having a person knowing they were protected. The current version is definitely an improvement on the previous versions though.
There usually are enough supporting classes in games to the point where the CW isn’t recognized or valued. His recharge ability would probably work better on a neutral class like Alchemist (being a potion of rejuvenation rather than a spell of course).
Maybe give him the ability to teleport other players and swap their locations during the night? He is far too passive in his current state and needs a proactive and high reward ability.
