Look you can kind of get away with it on Rainbow Six Siege but on a game that plays on your reactions p2p just doesn't cut it. The problem is you don't have to just be quick against the attacks to block but then on top of the connection this is fine if your in LAN with a low standard speed but over the net the differences in ping from 40-100 it just doesn't work. Another problem with p2p is that what on your screen would look like a perfect parry can translate to other PC's as not as it takes longer to get to their PC to process. You have turned a great game into an okay game just by not including something that should be obvious, come on ubisoft it doesn't take a genius to work this out.
