I rarely ever post on the forums; I think it was over a year ago was my last post and before that was even longer, I believe. Anyway, I only play BG and I play between 7000-8000 rating.
There will always be tribes at the top and tribes at the bottom. However, to say that Quilboar are out of control is an understatement. If you want some hard data to support this, go ahead and look at the win rate of Quilboar compared to ANY other tribe out there.
When you play Quilboar you are essentially driving a 300-thousand-dollar Maserati. When you play any other tribe you are driving a 1992 beetle with the windshield smashed in and the side mirrors hanging off.
