I did a search and saw nothing since update 6 hit yesterday about this. I guess they added a zero on to the critical percent chance, now the logic of higher is better still holds. But to see a 371% chance or in one crazy case a 871% chance to critical is confusing, I simply moved the decimal up a spot so 371% became 37.1% and 871% chance came 87.1% (still amazing and not sure if I believe it but that was the claim). If you are a new player or a returning with a higher level who has to readjust this is just going to confuse if you are thinking every attack/heal should critical.
