Function 1
-- "lowered armour class for all entities by 3 (fewer misses on both sides)"
Function 2
-- "weighted dice in dialogue (proficiency and expertise bonus is doubled up to a maximum total of 8)"
Function 3
"Classes receive boosts to scripted passive checks" (clerics and paladins will be boosted on religion, druids on nature, rogues on Insight, etc. The goal is to reduce OOC knowledge mishaps)
Is that what karmic dice actually does? I've never been sure. Function 1 does seem a weird one if so, and not something that someone who wanted functions 2 and 3 would necessarily also want.
Karmic/loaded dice shouldn't even be in the game. It was just a kneejerk reaction to people complaining about missing.
No problem with including some sort of loaded dice element if that is something that would give some players a better experience, though I do think it should be turned off by default. Right now, I think it's on unless turned off.
