What affects the block stun? I know weapon weight has a big role in it (especially massive difference between weapons) and maybe STR, but is there anything else. Damage perhaps? I've been playing 15/14 PS builds with heavy weapon (4.4 weight axe) for some time and didn't experience many "free hits" due to block stun of my opponent (talking about 1H players). But as soon I've switched to 1H (1.3 weight, 30/15 build) started experiencing it, especially against AGI users with Miaodao (2.1 weight) and stun was epic.
