Specifically in the fight against Zhalk.
I've played this fight a very very many times now, and with weighted dice on the MF hits fairly often and it's relatively easy to defeat Zhalk and the Cambions.
With weighted dice off the MF rarely hits, and without using all the tools at the players disposal as well as Us Zhalk just wins easily if you let it play out almost every time.
Is there any general issue with either the RNG or with Weighted Dice?
