Tbh, I have never been criticized in game. Ever. I'm not even joking. Probably because I don't really talk to people, play in fcs or do Savage. In reality, I am my worst critic (I am a 3D artist so ofc I am :P ). I did plan on doing Savage (I had beat O1S once) but on one party finder I put together for O1S we just could never beat the enrage timer. Obviously something was wrong so I went ahead and attempted SSS with RDM and discovered that I just could not beat the timer on that dummy for O1S. I was pretty discouraged so I went ahead and asked for advice here on what I was doing wrong, even recorded a video and posted on YouTube just for the sole reason of taking criticism. While all the advice and criticism was nice and helpful, I still sucked and never did improve so I stopped playing RDM and now play WHM. I still don't get criticized, even if I make a mistake, but my playing as WHM I feel fits me better than RDM ever did.

But uhm TL;DR, I take criticism, sometimes crave it because I'm a 3D artist, its my job to take it lol. I will listen, if its good criticism I take it to heart. If its bad or not constructive at all or its rude just to incite drama, I ignore it and tell the other person to piss off. :P
