Tanking isn’t really fun though, even though you may say you can have your fun and tank.
I have to fall back to queue times to reliably identify what’s fun to play.

I don’t want to get into specifics, but tanking ranges from boring to stressful.
You take too much damage and you’re healer get mad. You take too little your healer get sad.
I can appreciate that you want to feel like a clutch necessity, but that’s exactly what I mean by people-pleasing. That IS people pleasing.
My recommendation to healers that want to feel needed, is play whatever the queue gods says is needed. (Notahealer)
