WTS!: In-Game Loot Distribution

We're all familiar with the typical loot options in the game. I think the two that get used the most are Group Loot and Master Looter. I don't know anyone who uses Round Robin or Need Before Greed, and Free-For-All is pretty much a gimmick option for running lowbies through things, or similar off situations. I would like to see implementation of a loot system by Blizzard for raids, so there is a "standard" method - even if Blizzard makes it optional.

In my mind, a player should have an "edge" when rolling on items for his spec and professions, as well as when he hasn't received any loot from a boss (or raid) over multiple kills. Of course, this can't "carry over" between guilds, so each raid would have to be tagged for a guild or as "PuG" when entering, and each player would have a running tab of what amounts to DKP with each guild he runs with, while PuGs remain how they are now.

As an example of the mechanics, let's say that the bias for a player who can use an item is +5 to a roll, and the bias for not having won something yet is another +5 per boss. So in your Sunwell raid, the engineering goggle upgrade for your character's class and spec drops, and you haven't won any loot for 5 kills. So you have a total of 30 points to add to your roll. What I'm suggesting isn't a straight addition, but simply an increase of top roll - so (/roll 1-130) instead of the normal (/roll 1-100). These additional points would be "spent" on a winning roll, but retained on a losing roll. This puts a soft cap on the amount that you can effectively use, and so encourages people to roll often without making any points over a certain number useless.

This also leaves a large part of the loot to chance. The roll isn't being sold to the highest bidder, it's being biased toward the unlucky. There is still the chance for someone to show up, roll 100 on everything and leave, or for a dedicated raid member to lose every roll, even though he has a bonus of 500, but these are very unlikely situations.

Of course, a huge dilemma with this is that there is no "standard" system now, so how can Blizzard choose one to impose? That's why I suggest that it only be mandatory in a PuG setting, and can be turned off in a raid to allow a guild to use whatever system they're already using. I don't really expect to see this anytime soon, but here's hoping!
