I have another post GU4 issue - weakness.
Pre GU4, weakness exploit damage was the same as hit exploited it.
For example, if Ashen Hand hit was 5k, exploit of soul wracked was 5k hit too. I used it a lot to upper my damage.
Sadly after GU4, weakness damage changed:
[20:12:49] [20:12] You exploit the soul wracked weakness on Tehatamani Scorcher, dealing 730 additional damage.
[20:12:49] [20:12] Your Ashen Hand VII hits Tehatamani Scorcher for 4241 (2802+1439) damage.
[20:13:12] [20:13] You exploit the staggered weakness on Tehatamani Scorcher, dealing 386 additional damage.
[20:13:12] [20:13] Your Crescent Kick VI hits Tehatamani Scorcher for 918 damage.
If this change was done on purpose all weakness system is useless (at least for monks) now and can be completely deleted from the game
