I know what that you didn't really mean to suggest that everyone who does jump doesn't care about fun, respect, etc. but if someone chooses to jump even after asked to stop... its their choice in the end, they are good at it let them do it, can just log out if its really that big a deal.
Circling/running around is pretty much the same as jumping around them. It IS possible to hit them with swords both ways. If you take someone into a pvp and have them run circles around you and you rotate to attack them then have them do the same motion but this time JUMP... you will be able to hit them both ways. It just appears harder to attack the jumper since he/she is moving up and down as well as around. What I meant by take someone to a pvp... have someone stand infront of you, if they aren't jumping of course you CAN hit them... but if you tell them "hold down space", guess what... you CAN hit them as well even when they are IN the AIR.
Also, if you have problems with jumpers heres something I learned from pvping them many times. DON'T use the arrows to turn, use WASD. Right click on the mouse to adjust your aim as well. As simple as those sound they are a BIG help... being able to move in circles/jump doesn't have much to do with skill other than being able to aim for your opponent
