Critical Damage Bugged on PS4

Hi.
I would like to report that critical damage is bugged for me on PS4.
My critical hits only do a fraction of the damage they are supposed to do.
I have tested this on the practice dummies in Kyovoshad, and equipped/unequipped the critical damage glyph to see the difference.
The critical damage seems to scale somewhat with higher critical damage, but only fractionally. I have tested this out with 3 different level 100 characters, and they all have the same problem.

At 100% critical strike damage, it seems that crits do about 30-50% more damage than hits, at 400% crit damage about 60-70% and at 700% crit damage they do about 100-120% more damage than hits.

All in all, critical hits only do a fraction of the damage they are supposed to do. And it seems that I’m not the only one that has experienced this issue, considering this post:

Considering his issues arose when he moved to the eternal realm, it could indicate that this issue came with one of the season patches.
For me, it seems to have been an issue since i started this season (I had a long break from D4 before season 4).

Please, please look into this issue, its quite limiting, as the whole game revoloves around having a high DPS.
