I occasionally duel. I primarily duel friends only. Anyway, I pass by the outskirts of mournhold to drop off or pick up undaunted quests, people invite me to duels, I decline because I'm in the middle of something. Some then follow me around and do the laugh emote, teabag nesr me, or say stuff like " cmon duel me so I can pack you up"
Another time was when I dueled my CP300 friend in front of people. When I'd beat him people would then invite me, to which I decline, then they say stuff like " you duel a cp300 why u no duel me" stuff then go on and on about it.
Sheesh there's over a million active players on eso, do duel one of em. But many get mad when I decline them.
