onehanders are beastly. They are already faster than 2h & pole, they just feel slower at first to people who mistake the less length as being slower since they never get the first attack.
I don't know if you have ever seen ManOfWar or Cyranule as a 1hander... That is terrifying. I for one am glad Cyranule has been playing a 2hander, he is easier to take down now.
if you think onehanders are slow, watch ManOfWar, Balbaroth, Dan_ATS, Cyranule (when he is 1h), Midnighter, Matey, etc. [If you are NA]. Try fighting them with a 2hander/Pole.
I think you'll see that it is just your timing that is off, or your footwork letting people circle you a bit.
Speaking of Cyranule, I can beat him in a duel when he is 2hander maybe one out of 15 duels. When he is a onehander? It is a fluke if I win. It doesn't happen.
