Without much knowledge of coding, but It´s simply a priority change I believe? currently it seems to check if a critical and weakness happens only for the weakness mementum gain, no matter how often you tirgger it.
So after the first time you gained one momentum from weakness, it will never come to the part were a critical momentum gain, which is a problem with elemental weapons.
I think resist actually behaves like you expect it to. Gain 2 from the crit, lose 1 from the resist=+1 in the end.

I still believe, given how hard it is nowadays to trigger a "Weakness!" that a +3M with fleur is deserved, but atleast hitting weakness not being a punishment would be nice.
