Explain.
Being able to attack from multiple directions hardly seems clunky [as opposed to button spamming and special strikes (whirlwind strike)]. Requiring that the user put together a chain of attacks to defeat armored foes hardly seems clunky.
Swing speed isn’t enough to slice a fly in half in the air. Don’t know why that’s slow or not realistic. You swing metal whilst encased in metal. Medieval melee combat didn’t have the fluidity of ballet or a Hong Kong kung fu movie.
Perhaps you mean time to kill is slow. One strike kills were a thing easier in the release; they have been dramatically reduced. Not sure why this isn’t realistic.
There’s an occasional lag in what I call initiative strikes, but after that, the game reacts to block/strike control commands. So, not sure why overall you think the cambat system is slow
