priority is a balance of the points you earned, minus the value of the gear you have claimed, so whenever you claim gear it not only lowers your dkp value, it also adds a negative value to your priority
simple example
raid=100 points
ring value= 50 points
you should now have 50 points left, but the ring now adds a - value to your priority so it is now say 40
not exactly how it works but you get the idea :p
points also decay, for example points you earn in a raid, will lose 10% ov their value a month later
lol, what's funny is that only a few Ava members actually took time to understand how our system works. I guess the bottomline is that they all trust it enough and bought into the system and understood that it addressed a lot of issues related with loot distribution within a clan.
First of all, the points you earn from a raid only lose value through decay. I call them Effort Points or EP.
Second, each item is assigned a "gear points" value and when a member takes an item, they are given Gear Points or GP.
Priority is calculated as EP/GP.
Thus in Pigman's example, if you have 100 EP and you take an item worth 50 GP, your Priority is 100/50 = 2.0.
Another member with 130 points who took an item worth 30 points will have a PR of 130/30 = 4.33.
The following raid, both EP and GP will decay at a rate of 5%, so whilst PR remains the same, the EP and GP are reduced.
In Pigman's example, you will have 95/47.5 = 2.0.
The other member will have 123.5/28.5 = 4.33.
If the raid is worth 10 points, and the other member takes another item worth 30 points, his PR will change as follows:
(123.5+10) / (28.5+30) = 2.28.
While your PR will improve to:
(95+10) / 47.5 = 2.21
As you can see, even though the other member has taken 2 items (worth 60 points total), and you only have taken 1 item (worth 50 points), you still have a lower priority because the other person has attended more raids and deserves more loot for his effort. But if the other person took a more expensive item, perhaps you will have the higher priority.
Eventually it balances out, and the system will have a healthy loot rotation - which is exactly what it is, only it's not a simple round-robin rotation, and the more active members typically end up getting more loot than others. Although sometimes the more desirable items also end up with less active members and that's one part where luck plays a part because the good drops aren't very common.
An example of this was back in the Aggy days, when our active mages were taking Shadow and Void Grimoires and bracelets, so their priority went down. Eventually the highest priority mage was the least active one and a Godly Assassins Luring ring dropped and ended up to him. Now that mage has quit CH and since it was bound to him, we never can use it again for another clan member.
