I'm blocked from having a higher combat rating

I play Diablo Immortal and I have a problem with the values ​​of the combat coefficient of weapons. I am currently at master level 358 and from at least lvl 40, all the items I find or win have the same combat coefficient, and often even lower, which is why I cannot develop even though I have a higher and higher master level, I increase the values ​​of gems, weapons, reliquaries, etc. The weapons I find or win, even if I create them myself, their combat coefficient does not increase. It doesn’t matter whether I’m on Hell III or Inferno 1. Please explain what’s wrong and why I’m blocked from having a higher combat rating. I repaired my account. I installed it again but it doesn’t help.

This thread explains, in painstaking detail, all the sources that Combat Rating comes from…

…and all the ways in which you can increase it.

It absolutely matters, as the max CR of items dropped in Inferno 1 far outstrips the max CR of Hell III items. As an example, here are two INF1 set items. The first is triple attribute / triple magic affix, the second is triple attribute / double magic affix…

Low-end INF1 set items, i.e. double attribute / single magic affix, would have around 1830 CR. So, the difference between those and a high-end set item is 1914-1830 = 84 CR. Eight slots of that sort of difference = 8 * 84 = 672 CR.
