The group was not a 'LFM reserved'
He tried to reserve once group went in and was told no reserve. I do not do reserved runs for the same reason as you; fair play on upgrades. At that stage he obviously decided to use the group and ninja instead.
This charmer was advised by the rest of the group no reserve on gear; instead of being an adult he ran the group then changed to ML and ninjaed the drop.
Party up with him at your own risk:
I've made a horde side 1-3 exploration guide here:
You can take this to 1-4 in a bit over an hour if you also run to Mulgore/Thunder Bluff and go into Silverpine after doing undercity.
