Is needing for OS "Ninja'ing" when MS people need the item?

[RainyDayProphet]

Am I the only one sick of people Needing on items for a spec they aren't playing (when a Main Spec person needs)?

After 15 or 20 runs in dungeons to get an item it's pissing me off.

Is this ninja'ing or should I be needing items for my OS as well?

for rdf needing on os will get you banned if reported. it's need for ms and greed for anything else. in raids it depends on the raid loot rules.

For the brew event ****? no, cuz it's farmable event

For ToC 5 trinket farm or any RDF? YES it is ninja
