To me it looks like it is to address the miss miss miss issue that gamers on another side will complain about it because it's a common complaint in TB games.
As long as you miss one 80% hitchance after the other, there is an issue with that.
I have the feeling my chars hit more often, when the chance is 20% than 80%. But in total they hit much less than the hit chances would imply, as like the displayed chance is just wrong. That feels so weird.
