On top of a lot of other people's perspective on tanking, I would also recommend to ignore those who call you garbage. A LOT of those people have never tanked or don't know what they are talking about. Don't take what they say to heart they are just assholes who are full of themselves. I'm a 61 PLD main and my early tanking days I remember this guy who was just a complete dickhole. He constantly bitched about me keeping agro during bosses... when those bosses randomly attack people. He also complained that I didn't use flash or anything, called me garbage, he was a complete idiot who didn't even know the mechanics of bosses. Anyways, people like to bitch just to bitch. Ignore them and have fun. I refuse to play with people like that. I will leave a dungeon as soon as I hear ANYONE talk shit to me, instant ignore and leave. They can then spend 10-15 minutes looking for another tank.
