I have a few of the old invasion 40-50 ssi weapons still sitting around and decided to break out a warhammer and imbue it since it now has a higher imbue cap. The problem is the weapons from that event do not trigger parry. I have done multiple tests to confirm. The last test i did that really confirmed it for me, was i had my friend on his archer shoot at my sampire and I didn't parry a single shot. At least 20 shots in a row, no parry with a 2 handed weapon, 120 parry 120mace 120 bush. So I switched to another weapon and bam, 2 parries immediately and then back to 40% block, which always seems to trigger more vs archer. Basically these weapons are useless right now. Why use a weapon that can't parry?
