In what bizarre parallel universe does slower combat speed favor 2h spamming? It does the exact opposite, the 2h animations are easier to spot and block. For one, I think your problem is that you keep trying to be the first to attack and when going against a longer weapon, and this will get you killed. You need to block and then counter, which in my experience playing this patch it just as possible as with the last one and the one before that. Also, are you sure that these 2h people are "spamming" you, or is that just what you call it whenever a 2-hander beats you easily? What behavior qualifies as "spam" in your mind?
I for one still find 2-handers much easier to beat than someone with a shield, and people swinging wildly are more often than not free kills.
