I don't usually post, but I've been browsing this thread off and on for the past couple of days... I've seen 'loot ninjas' in a few PUGs, but I'm one of those that very rarely rolls need or greed on anything; my Sorc healer is geared enough to run the flashpoints and hard modes that I like to run, so I usually just let everyone else have a go at it... I've even told several groups, when they bring up the loot rules, 'I'm passing on everything; you guys have fun'...
However, I've also been on the receiving end of anti-ninja rage: I was running with a PUG in Foundry and a chest piece with Willpower stats popped up... I was either a fresh 50, or just under 50, and the stats on the chest were an improvement on what I was wearing at the time, so I chose 'Need'...
I was told that piece wasn't for my spec... I explained that it boosted my Willpower and another stat (Crit, I think), which my spec uses...
I was vote kicked for being a loot ninja, even though I don't think there was another Inquisitor in the group...
