As Halycon succintly summarized in his replies, Karmid Dice is the poor implementation of an idea that was simply FUCKING AWFUL to begin with.
There's NO sensible reason to have that option on by default, and there are very little reasons to turn it on in general, even if you are some peculiar flair of masochist.
Sure, so I didn't turn Karmic dice off, but went to the spider hole next to the grove to see what happens. First round, we got a critical miss. The chance of not having one critical miss in 4 attacks is 81%. But I still got one, after an avalanche of them at the grove's fight, just before.
If you want to talk about masochism, then rejoicing in crit misses about every turn would count IMO.
