Just made lvl 10 for the first time (whoop!) and I was having a conversation in the Lady's Rest, when I got the message that because my lvl is to high that the xp I would receive would be lowered.
This is very strange to me, I think it should not matter what lvl you are when you're just talking (no matter to who) it's not like you learn less.
I get that the original idea was to have characters of other lvl's on other sites, but most places are deserted and a lot of people start or hangs around at the lady's.
