I personally find it wrong that people get ranked after 10 games.
There are people who just played 10 games in the first days , and never played pvp again, and still it is is impossible for us to reach their rating!
In my Guild my team whas an average rating of 60%. So a friend of us buys the game. He still has absolutely no idea how to use his Guardian, but after playing with us he has 11 wins and 2 loses , and a rating of 85% because he plays only with us, while the rest of us try to help all guild members learn pvp.
I thing there is something wrong with that… Rating should be applied after much more games IMO.
