When is the emotion system going to be refreshed/fixed? It's so unbalanced :(

I use a mod, which you've said you don't want to do.

I remember an occasion in one save, where there was a married couple and the husband's parents living together in a house with a cat. The wife had a child, and shortly after that the cat died. It was like a constant musical medly:

VERY HAPPY! (NEW GRANDCHILD!!!!!!!)

VERY SAD! (DEAD PET)

*Grim rolls in*

VERY HAPPY! (NEW GRANDCHILD!!!!!!!!!!!)

VERY SAD! (DEAD PET)

VERY HAPPY! (BIRTH OF A CHILD!)

VERY SAD! (DEAD PET)

*Grim reaps the pet*

VERY HAPPY! (BIRTH OF A CHILD!)

VERY SAD! (DEAD PET)

Flip flop flip flop flip flop flip flop.  Also, being very happy at the sight of Grim arriving to reap your beloved pet makes your Sim seem unhinged, or like a psychopath.

Sims shouldn't flipflop between Very Happy and Very Sad.  They should have a mood somewhere in between that changes gradually.

As if to make up for the callousness of the joyful VERY HAPPY music, the husband's two sisters came to mourn at the urn every day for over a Sim year and I finally gave up and used an ambrosia treat.
