Is this classified as NINJA-ing?

Good Day Game Masters and Readers!


As you can see on the images provided, I rolled for Bone Sentinel Amulet even if the raid leader told that only MS heals roll. And, as most warlocks know, spirit is needed by this class also because of Fel Armor and Glyph of Life Tap. ....., the SHADOW priest with whom the leader gave it wasn't even a healer:


Technically, I won the roll, but ...., the raid leader, still gave it to this ......

Please do note that there were two (2) Bone Sentinel Amulets that dropped from Lord Marrowgar:

Wherein the raid leader didn't specified the roll for healers.

What I would like to know is that, is this classified as ninja-ing? Considering that my class needs the item, and the leader decides to give it on healers, and YET, gives it on a SHADOW priest. If this is ninja-ing, please do the necessary sanctions these people deserve. Hoping for a positive feedback as soon as possible. Thank you for reading.

This isn't up to players, so has no point being in the Forums - especially with screenshots showing names. If you believe it was, make a proper report. The GMs' opinion on the matter is the only thing that will have relevance, not what other players say.
