you know, when a guy is running past you, it's pretty safe to assume he is online and able to respond.
edit: guess I'm wrong. you still have to warn them even when it's dead obvious they're online. So, "Have at thee, don't get a heart attack, because of the surprise, because I'm about to poke you with a sharp stick!"
edit 2: oh wait, actually you have to offer them an alternative to PvP too. So maybe this line is better: "Have at thee, don't get a heart attack, because of the surprise, and because I'm about to poke you with a sharp stick! Or alternatively we can go to the pub and discuss it like grown men over a pint of raspberry juice with cinnamon!"
I suggest you macro this line to make your
UO life easier.
Oh and this is not a dig at CoRE. We used to have funny rules like this on Cats as well... yay nostalgia lol
