Player rating for tournaments across all installments of Heroes.

Quoting my post #116:
"There are two players - A (rating 850) and B (rating 250). For winning, A will receive 100. If B wins, he will also get 100 (regardless of rating). BUT: as a result of aging, A will lose 85 in any case, and B will lose only 25. In total, A will earn 100-85=15 points in the best-case scenario, and B will earn 100-25=75 points in the best-case scenario. This is what I call a greater burden for the leader... "

Is that right? Worked hard and got nothing? Is that fair?

Yes. You've accumulated a high rating - now you have to work to avoid falling. :)
There will always be those who want to climb to the top - a vacant position will not remain empty. :) How else? So that the leader pulls away so much that no one can ever catch up? And if another monster like him arrives, but a couple of years later, on this resource. Without such an aging system, this newcomer monster would not even theoretically be able to catch up with the leader, even though he is equal in strength, but started later. And what should he do, wait until the leader kicks the bucket and disappears from the resource naturally? :)
