I did this Saturday night around 3 am . me and my group ( 69 priest , 69 warrior and 68 lock) were helping out my shadowpriest friend get his ring of blood quest done.
since i was first to land i invited him to group and started to spam for tank and healer and more dps with in seconds i got hits of people who wanted to join
we had 2 almost 3 full groups ready and lined up . and this is how you make money , keep spaming for a tank and healer ( most of the time people dont admit they have this quest or want to join in pugs at least on my server most of the quests i seen done were all guildies) .
after about 10 mins i said in /s that i found a tank but he is busy questing and so we have to wait . then about 5 mins later i said i pulled a priest who was 3 bars away from leveling.
summoned the priest and warrior who already knew they were coming and we did all 3 groups at a time thats about 10 people who had the quest and the other 3 who already done it .
with 3 groups we flew by the thing and everyone got there 66 gold lots of xp and the quest items . to which i whispered to the leaders of all groups to comment about the 2 69's stoped questing and everyone should tip the 3 people who made it happen .
having 10 people get a total of 66 gold as well as bad ass items got us about 120+ total in tips for 10 mins of work. a little planning as well as some other items like gems and other wise.
This plan works if you test the waters first as well as no one should be at the ring of blood while you are trying to get the groups together. when i went the ring of blood was totally empty yet there was 30 odd people in zone. out of the 30 - we got 10 paying customers.
to recap things you need -
/who nagrand 65-70
have a premade group ready who can do the quest.
get 2 groups of people who need it and have been trying to do it for days.
some good group cordination ( having everyone hand in at the same time is a pain if people mis match it .)
asking for the tip for the premade but not letting them know they set it up i would think is key . we did it after everyone was happy about getting 50k odd xp + 66 gold.
