Everybody is entitled to whatever loot is thrown into the game. Everybody pays a subscription, everybody is entitled to that content.

Throwing a tantrum because you didn't get some gear you wanted for a class you weren't even playing? It's hardly the end of the world. If you want a particular piece/set of gear so badly ask politely at the start of the dungeon or run said dungeon multiple times. Hell, I'm not even one of the people you seem to have such a vendetta towards (I'm hardly a veteran, don't really participate in desynthing/GC dailies etc) and I still think it's a pretty ridiculous idea.
