"only XL-4"

Where did that 18% come from? :confused:

The balance in Heroes is such that, in recent years, largely thanks to streaming, the average skill level of players has increased significantly, while the skill level of top players has become more uniform. That is, the skill dispersion has decreased, and therefore the distribution of game setups has a greater impact on the result.

About 7-8 years ago, a top player could even win against the second tier with a large score on a small map, and on XL+U the chances were even more incomparable, so XL+U was then considered the standard of balanced map generation. Now this is not so pronounced, even on mirrored maps, flaws are found, and non-mirrored maps are increasingly called a lottery.
