i usually dont give away items just like that
for example, i play alot in pre searing, i sell alot of charr bags
i am lvl 14 myself now, so already a bit above the usual pre searing lvl
i do play alot with lvl 6-10s, and occasionally (when i enjoy them and they are friendly) i give them the charr bags if charr bags drop... specially when i can see they are having inventory troubles
but i am not going to give it to just some lvl 1 standing in town.
i will give it to someone i played with, and someone i liked playing with
even if he was lower lvl. if the gaming experience was positive, i tend to be generous.
this was just a charr bag example, but it happens on other occasions too.
whenever i liked the gaming experience i had.
i also make a habbit of provoking players to say thank you
when selling charr bags, i usually add something like "thanks for the money, and may that bag be filled with loot soon", or "happy hunting, hope you enjoy the bag" ...
then you almost 99% of the time, get a thank you in return,
if you do this, i sort of figured out that players i trade more frequently with
always say thank you from the second trading time on.
so it has a positive effect.
