I cannot change the nameplate strata. This is a problem because me and my M+ group use the same weakaura to tell the group your thundering mark. The problem of not being able to change strata, is that nameplates have higher prio than chat bubbles, so they end up covering the marks. Not sure if this is able to be changed or not.

Yeah I wanted to chat bubbles to override nameplates. Ok tnx for the reply <3

There is currently no option to change the nameplate strata - if I remember, nameplates are already on the lowest one. I am not sure if it's possible to change it in a way that chat bubbles are no longer covered by nameplates (that's your issue, right)?
