I'm gonna play devil's advocate here for a moment.
Where you considering and applying any of the advise given to you?
I'm not saying the way he treated you was proper (idiots will be idiots, he's just another basement dweller who would never say anything like that to someone in real life) but sometimes, you need to understand, it really is frustrating to try and give someone some feedback or some minor criticism only to see it fly through one ear and exit the other.
I'm not doubting you know how to play the game (it's not that hard, let's face it) but maybe keep your mind open and try something different? Think about it, if you use his suggestions and die even more, all you can say is "I told you so"!
On another note, a bad player is someone who doesn't play the game and thinks he/she is actually capable of giving any sort of advice. Take from that what you want.
