Often people have asked for 1v1 arena, they want a chance to play alone and take all the glory, to be the great player doing it alone. Various reasons but always it is said the game is not balanced around 2v2 let alone 1v1 so how about have ratings in a ladder only compare you to others playing the same class. It could be for transmog gear but also titles.
I'd like to see the rating work much on % so your rank would be decided on where you were amoungst your class.
We would not see that but the internal system would see if you were in the top 50% etc and rank you accorindingly.
This is a rough idea but it should be easy to see where I am going with this.
If we are rated by comparing how we do to others playing the same class then the balance is not an issue. The overpowered classes all will do well so ofcoursebut there win loss ratio would have to be higher compared to an underpowered class to achieve the same level/rating/rank. It would all be a kind of passive handicap, but still fair.
