The Sharing System
The sharing system, while not unique, does affect various aspects of play. The most prominent of these effects is the experience points one gets from someone who is sharing with them when they kill a beast. The other effects are making it easier for a healer to heal you faster and how fairly coins are divided up among a group. It is very important to share a healer healing you. Healer shares take priority over other shares, except in cases where a mystic is with the party.
For each dispatch, kill or vanquish, the person being shared with (the sharee) gets 10% of the experience the person slaying the beast (the sharer) receives. The sharer does not loose the 10%, but instead gets a 1% or 2% bonus for sharing. Thus, if a person is sharing with 5 people (the maximum number of people you can currently share with) and slays a beast, they get 105% of the experience, while each sharee gets 10% of the initial 100%. The 10% bonus to the sharee doesn't continue on to whomever they are sharing.
Also, when multiple people slay a creature, the experience is divided among them. If they're cross sharing each person gets a bonus of 10% for each person who is sharing with them, plus their 1%-2%. So it's possible to get nearer 100% of the experience. In group hunts this adds up quickly, and people tend to advance faster.
To healers this 10% is how most get their experience. Also, when sharing a healer, it makes it easier for the healer to heal you, and you get healed faster.
If the creature slain has a fur or teeth that is successfully skinned/pulled, the coins are divided among the people who hit it and anyone on the same snell that they are sharing.
