Hi. PLD tank here. I had the same issue. A lot of the dungeons I run items drop that clearly a full upgrade. I understand the reasoning but the item does specified what class can use it. Initially, I thought this was just for "Disciples of War" rated item. Then, in Vigil, I saw a helm drop, and clearly state GLD MRD PLD ETC. I can't roll Need on that. The other team members were Disciples of Magic.. so.. even in that case, you can't roll Need on it.
The fact of the matter is, if an item is suited to a particular class only, the filter of the item should only list that class.
I strongly believe that this is a bug.
Below is an example of an item I won with "Greed" and cannot "Need" as an example.
