either some players are in bad faith or they don't have the knowledge. it can be imagined that those who play premade have the knowledge
1 - all guard damage can be parry, even from magical sources

2 - we can reach a huge defence against custody in 2 hours and which is not achievable in s&b. (exception BO with "cant hit me")

to reach the same protection rate in s&b it is necessary :
50 % block + 70% parry ...

this analysis confirms that you take less guard damage with a high parry rate than with any S&B configuration...

is it logical?
