Okay, what I mean is Crit Chance is a rather weak stat if to do a brief math:
Let's say your base dmg from normal hit = 100;
Let's say your current stats are: 100 Profi, 300 Det, 100 Brut. Let's say you maintain 100% Det (for simplicity sake)
This will increase your normal dmg to 100 * 1.1 * 1.45 * 1.1 = 175.45 (the effect of Brutality here has been counted equal to Profi, which is very close to the exact number, which requires solving some differential equations to accurately calculate, so we'll skip that, the game is EASY, remember?)
Now let's say you have 200 more stats to spare.
If you put them to Profi or Brut, the resulted damage will be:
100 * 1.3 * 1.45 * 1.1 = 207.35
If you put them to Det, the resulted damage will be:
100 * 1.1 * 1.75 * 1.1 = 211.75
If you put those 200 stats to Crit Chance, the result will be:
175.45 (dmg of a normal hit) * (0.8 (# of normal hits) + 0.2 (# of crit hits) * 1.5 (crit hit power)) = 193
---
So if you put 200 of those stats to Profi or Brut, you increase your damage by 18%
If you put it to Det, you increase the damage by 20.6%
If you put it to Crit Chance, you increase the damage only by 10%
Now why would you do that?
