You have got to be joking, OP. Is this, like, a joke/troll thread or something? You cannot possibly think you were being helpful in that chat excerpt.

Without even asking if they minded some friendly advice, you jump right into making demands to a complete stranger, about what spells you want them to cast. Then when they refuse to bow to your demands, you tell them to "choose another job"?? You are practically a half step away from "omg uninstall plz gtfo."

Your "you just said you don't want to do your job" comment is borderline delusional. It is like you don't even understand what is being said to you.

Not to mention, it matters very little if your advice is correct or not, if you don't bother to explain why. Without the why, it is not advice -- it is just an order. And you are not in a position to give orders, whether it is what class to play or what skills to use.

And finally, when they flat-out said they do not wish to be told what to do, you just keep at it and harass them incessantly. Please, if you can't be more courteous/respectful towards others, at the very least learn when to quit.
