do not make uniques like rifts - rifts need to be repaired, as point system on rift is a completely fail, because it reward just for targeting mobs not need to do any damage... it should be based on damage done for mobs.
when me and couple frinds started that game many years ago we was killing 1 wolf by 5 people - that was for new players, so if new player cry loudly because he see when others killing a dragon, and he not get anything from it, it is silly.
small group will an;t kill a unique if they use crappy weapon and other gear, have gear good enough takes lot of effort.
hunting for a unique usually takes a lot of time, sometimes was riding around map for 16 hours and find nothing, by many people in many days, and finally find that one unique mob - and after that some people want to share it with everybody, even if they not moved body from deed?
i think curent system works fine, it allow groups of friends to do some kind of hunting together, and if the group want they make public event (which i not especially like because of global lag when hundrets of people travel at same time).
everybody can join a hunting group but starting relationship with "take me to unique killing group" will not work i think everybody have couple friends who might be interested in forming another group and join that fair and nice competition
currently there are couple active hunting groups, and we not see others as enemys, we are friends who just compete
and for those who not understand mechanics of scale/hide distribution:
if someone think dragons just give to everybody 0.02 not matter how many people will be at slaying is completely wrong
drake gives from 0.50 up to 6.00 kilograms of drake hide split in equal pieces between all people in local
dragon gives from 2.00 up to 10.00 kilograms of scale
many times heard from people "why do you make them private? isn't better to make it public to deliver to game 200x 0.02 instead of 15x 0.02?" <--- calculate again
