Guild Wars 2

First of all let me preface this by saying that this is not a QQ or rage thread.

I simply want to ask this question:
When rating is fully implemented next patch, will it be account-wide or will each character have its own rating?

I only ask because I know there are those of us that would prefer for it to be character separated, simply because we are not on the same skill level with every class we play and we would not like to have our rating affected by the few tournaments we play in our offclass.

Thanks.

Class based rating would be awesome. It would promote playing with different classes, raising all your ratings and who knows, maybe purchasing extra character slots?

Also, will the previous to patch games you played count for rating? Or will everyone start at 0 rat?
