Correct, you can only greed on it.

I think you might be able to roll need only if you have a profession leveled high enough to the point you can use them. So around level 500, I guess. I'm not really sure though as I've only been able to roll greed on my Druid. Guess I'll find out on my Mage soon..

Last night you were able to Need it on the one dungeon run I did. I was surprised by this, because I expected them to change to be just like the WotLK orbs. Maybe they have hotfixed it?

At or about 7:30 EST last night, I could only greed orbs. This was on my 525 Leatherworker. The need dice were greyed out.

Huh, my run was at about 11:00 PM EST. I'm positive Need was available. However, the loot ended up bugging out and no-one received anything. Perhaps it was just a bug.

I have tailoring maxed, and I was only able to roll greed, not need.

If the dungeon finder had to pull a random person in, then you'll only be able to greed. If all 5 of you are preformed, then like any other item, whether you can equip it or not, you can need/greed.

Oh, duh. Mycroft nailed it, it was an all guild run.

If you enter a dungeon with five people you know, the need option is available. If you pug through LFD system, it's greed only.

That's how it worked for me yesterday.

The dungeon that I did with 4 guildies only let us roll greed on them... and yes, I have maxed crafting professions... Now, we did use the dungeon finder to get into the instance, we didn't hoof it there. So maybe that makes the difference...?

It was elected to greed, not to need.

How do you get six people into a dungeon?
