I called your behavior childish because you got pissy at Blizzard for not making the changes you wanted them to make. That IS childish.
I'm not a musician so i wont pretend to know the ins and outs of that indistry. But having a 15 year career in music and refusing to take any feedback seems stupid as fuck no matter what profession you are in.
Like objectively that just doesnt seem constructive.
Every single time you go up on stage and play you are asking for feedback.
