First, it takes 6 items, not 7. Inform yourself a bit before calling someone a liar and then give some incorrect information, please.
And second, just if you're curious: Grab 30+ players in groups of 8. Tag the mobs and get them to the zerg (easy, as they're usualy pretty close). AoE kill them in 1 second, everyone gets credit as they're in the group, thus receive their items. Go to the NPC and hand them. Enjoy the countdown. That's what I've been seeing today, except a couple of times that they waited a bit before turning them (props to these ones).
Even tho, I'll concede you that maybe it was not exactly 5 seconds, as I wasn't actually counting (before someone else comes nitpicking everything I say), but it was less than 10 seconds for sure. I was not overexagerating, no.
And no, I'm not complaining at all. I'm just stating what I see that's wrong within the game and how people behave. And it seems that I'm not alone. You can still do whatever you want, as I said I'm not going to stop anyone. But don't come complaining once SE has to take measures about something, as they've already done.
