It helps a lot when fighting 1vX to know a couple of things, parries reset when successful so you can keep doing it. You gain hyper armor if you riposte directly after a parry, if youve got bloodlust and decent hp left, just swing at the heads with that armor and pray you kill someone. Still this makes your entire survival completely dependent on a successful parry, and when fighting 1vX and one of them has a short ass weapon and misses, but you still attempt to block it, then you are fucked. It really feels like short weapons were not properly considered in the game, so much whiffing just makes the combat feel absolutely garbage when it otherwise flows kind of well with long ones.
Also cavalry is busted, more so than in crpg/native. You take no added damage on horse back, a clean perfect hit on a horse sometimes even does less than it would a player. And long weapons like the halberd on horse can literally swing on the left side and hit someone on the right for a one hitter quitter. I even tried to block it when it happened to me, but it just oneshot me. Visually i dont think it even gets close to connecting, its just a massive cone of death.
