Being a rare class is a loot boon in the Lord of the Rings Online™ raiding environment. Tell me if you are seeing something similar/different in your game/server.
First, understand that (at least on our server) raid loot is awarded by a standard need/greed roll. I know of guilds that use DKP and such for their guild raids, but the game is very supportive of casual raiding, so I have never been on a raid that used anything other than need/greed (with master looter enabled). This does give an under-equipped character greater rewards for raiding, but no one seems to care much. Even if there were DKP, how many would you need to spend in competition with your guild’s other level 60 Warden?
We noticed that we had a dozen level 60s on last night, so we called in impromptu turtle raid. Our team make-up was rather good without much fiddling, despite what looks like a ridiculous class balance: we had 6 Hunters, 2 Minstrels, 2 Burglars, 1 Guardian, and 1 Champion. For the non-LOTRO players, the turtle raid calls for tank rotation due to a stacking, incurable DoT, and the easiest way to do that is with a Burglar’s Enrage ability, which makes the enemy attack at random. That makes everyone a mini-tank, spreads the damage, and makes it a race between your DPS versus growing damage-over-time. The ideal team would probably be 10 Rune-keepers, 1 Burglar (for Enrage), and 1 Loremaster (for fire damage debuffs).
As one of the 6 Hunters (before dropping to let a Captain join), I realized that my odds of getting loot were not great: 1/9 that any item is for Hunters, then 1/6 that I get it. Hunters are the most popular class, so every group of six for every raid will have at least one Hunter. Minstrels have a similar problem, caused by their necessity rather than their popularity. Meanwhile, if you came to our raid with one of the other seven classes, only a Burglar would have needed to roll to take home his/her class’s First Age weapon. I have not checked how the raid turned out, but that was a greed roll if the drop was for 1/3 of the classes.
A similar factor explains why Hunter items are always ridiculously expensive on the Auction House. For every person who needs a good Warden javelin, three need a good Hunter bow.
