Well, the first thing to mention is that we do not use DKP, or any other "currency-based" loot system. We use rolls, and common sense - we have a designated master looter (Currently me) who handles all the loot and interferes when needed. More information follows below.
How does this work then, and why do we use it?
Well, first, why we use it is a simple thing to answer. We gain more as a raid force by using rolls. The problem with currency is that people save it up for those amazing items they really want - usually some weapon, or something with an orange text. With roll, people get greedy and want every single item that is an improvement. Even though we despite loot whores in the guild, and that they DO NOT LAST LONG, this is more or less what we want - people to get geared up, and squeeze every bit of improvement there is out of the gear.
How does roll work in a huge raid?
Well, it doesn't. It only starts working well, and really well I may add, when you got a masterlooter with common sense to be there and distribute the loot. At the moment we haven't really had many real occasions when it was needed, but I've stepped in and discarded the rolling system some times. For example - I already had an epic weapon, and Death's Bite from Kel'Thuzad dropped. A Death Knight had some really crappy blue weapon, which meant that he got the axe - and would have, even if I rolled 100 and he rolled 1. I agree with you, this is a rather stupid example since I was the person who passed - but the core of the message still remains. People who need loot greater than others will get it, and we won't use rolls. (Note, greater. Not just more, it will have to be a huge difference in order to bypass the rolls.).
Do we have any other priority system? Main tank, main healer, and so on?
Not like that, no. All the tanks are entitled to roll on loot, and we will never give loot to a specific tank, just because he's the main tank. Same thing with healers, dps, and what ever is between. The only thing we have, and most guilds alike, is that anyone in the Trial rank will only be given loot when no accepted member has got a huge need for it. Of course, the trial will get the item before it gets rolled on for off spec. This is something that every Trial will need to accept before coming to a raid.
If you join a raid, then you acknowledge that you're familiar with this and that you accept it. We do NOT want any mid raid fight about some stupid loot. Like it or leave it.
