Actually, usually you ask most of the time for a coach to get better at the game and learn other peoples type of skills. You don't get coached to learn how to get better, you already know how to play. As long as you know the controls for the game, you'll make it through. But to comment on only making the account to get better, do not say that. There may be mean people and nice people here on the forums, but you should try looking harder. Try asking people that aren't just saying "Hey I'll help you get better." Because most of them can't help you. Your best option is to start playing in teams.
I look at your post and I think "Jeez. She's really bringing down her self-esteem. Isn't she?" But that's the problem. You're relying way to much on other members. All we're going to give you is tips, advice, and explain our tactics. That's it. We can't do anything else about it.
You aren't a bad player, you're the average player I've seen people that are extremely terrible. You are basically a god compared to them. Don't lower your self-esteem. That's bad for you. Everyone here cares for you. The best we can do it play by your side and point out some of your flaws. That's about it. I'm sorry, but that's all we can do. Unless if all invited you over to our living rooms and taught you how to play in person and explain it through there, that's the only actual way you're going to get better. Which probably isn't possible for most of us.
Hope my feedback helps you any.
