A couple of my raid leaders seem to think that taking loot-locked characters on a raid somehow diminishes the loot chances for the rest of the group. e.g. a raid of 15 people will stand a better chance of getting loot that a raid of 20 people where 5 are loot-locked. This doesn't sound at all right to me, I'm pretty sure the loot-per-person when considering the 15 eligible ones would remain the same in both situations (allowing for random).
Are there any developer/blue-posts anywhere that would clear this up? Been trying to find something but haven't had any luck yet.
