False. Ninjaing actually meant people who grabbed loot right off the ground when they weren’t supposed to if they didn’t set the loot correctly. Even in vanilla there is a video of someone ninjaing the loot off an Ony run. So for example you kill a boss and all the loot drops and there was no rolls etc. then anyone was able to just take the items even if they couldn’t use them and not allowing the group to do /roll. That is called ninjaing.
How is it if people roll need for a mog/offspec that is called ninjaing to you? They put in the same amount of time and effort as you and if they want those items then they have every right to roll need also.
I swear, the new generation of gamers today love changing meanings of what terms actually meant. From ninjaing to p2w etc.
