I know I can hardly do very well if my ping is 70+ as a Ninja. Blocking, movement and hits become very unpredictable.
Less than 60 is OK for 2 handers I think. Archers and shielders and horsemen might have a different story though.
I think it belongs in the newbie section, cause it's really important to know what playstyles are sustainable for your ping. (Like, it might not be you, but your ping!)
What's your experiences?
