Today after some matchs i detected some irregularities, the free guard break after a parry was acting strange vs assassins when using some characters. So i decided to make some tests
To make the test i used a level 3 bot (they counter almost all the grabs) this allowed me to erase a ms problem of network (as i was playing with 0 ms) also im using a perfect guard break (after a succesfull parry, tap UP + GB and hold it, that way the hero will make the guard break with no delay) this free the possibility of a bad user.
Then i picked warden and some other characters, the results are as follow.

Currently (i didnt test all the characters) the heros that can exploit this bug are the peacekeeper, the berserk and sometimes (its random in his case) the orochi.
This exploit only work if you are vs some of the intermediate (valk, warden, etc) character or almost all the heavy characters (conqueror, raider, etc) warlord is an exception (in my tests it didnt work) if you are playing a light hero vs light hero match the bug will not work, it also happens when playing nobushi vs peacekeeper (thats why i did all of this tests)
if someone have some questions feel free to ask, as i was saying i used a perfect guard break (i explained how to do it) so player skill is not involved, only mechanical gameplay
If you can, comment in the video so one of the ubisoft team members can see this, as its a bug (im sure about orochi one, it was completely random)
