Choosing the official ranking on HeroesWorld.

Actually, I think the chess-like variant is better. Otherwise, no one will want to play with low-ranked players.

Playing with low-ranked players doesn't help improve your skills. And this will be an additional incentive for weaker players to improve their skills so they can play with better opponents. I've been saying for a long time that this is how it will be.

What if it's the other way around?

No, it's exactly like that.
