a question about the exp

[slavmaster]

just needed to ask something about the exp. is it like that , that if your in a party u dont get any exp if your to far away from eatchother? because a lot of times when im on my hp and in a party we can just teleport around and looking for the mvp or w/e we r gona look for and then i lose a lot of the exp the other one gets while killing monsters/mob/mvp.
so do u have to be close to eatchothers or is it just me that thinks so and why is it like that because it seems abit unfair sometimes?
