Player rating for online battles on full maps.

Regarding the topic - are we talking about calculating the tournament rating on HW?

Yes.

Is it planned to merge it with the league rating?

No one has raised this issue. In my opinion, it's not necessary.
Right now, the main problem is finding someone who would take care of the rating. But we need to calculate the rating taking into account the tournaments that have taken place since the time when the rating was no longer being maintained...
