I do it sometimes, not as much as others
With this turn speed "buff" to the longsword I may begin doing it more again!
It is amazing what you can do with a MW longsword (40 cut 100 speed) and 9 PS.
Most longsword users now have left swing->strafe+turn left->rightswing on macro or something. I'm using a 100 speed weapon myself now, and I still can't prevent being double-hit whenever someone does that to me. It's pretty infuriating.
Only counter I've found on siege is to just run along hugging the castle walls on my right side. The 12 o'clock to 3 o'clock quadrant is a dead zone for 1h-ers, so forcing that area to be masonry is the only solution I've found. Maybe the turn rate buff will allow me to overhead people in that quadrant, but that's still risky.
2h users don't understand what it's like to have half their screen be "people in this area will kill me if I try to attack them".
