To do some comparison on what this plays out to, about half of the players hunting for a single item on Pa'valek would get it in 3 tries. Greater than 90% of those players would have their item after 9 trials. 9 dungeon runs for one item is a run of bad luck, but nothing insurmountable.

Now compare to Viryx. In order for about half the players to get their item, you're looking at 47 runs. That's 47 hours waiting in queues, 10 hours of actually doing the dungeons. In order for greater than 90% of those players to get the item, you would be looking at 160 runs.

Those figures don't even factor in other players rolling on loot for their off-spec or whatnot. While perfectly valid, from the individual player's standpoint, other players in need/greed do nothing but reduce the chance of you getting the loot you're after.
