easy.
Person A Needs Baal Quest, and is lvl 20,40,60 wtf ever
Person B is the High-Level Helper
Persons A and B go and kill ancients,then baal.
anyone in act 5 at the time, in town needing Ancients/baal WILL get the quests,just sitting in town.
The kicker is, SOMEONE who needs the Q, will have to actually do the questing,whilst the low-level leechers stay in town,and sip pina-coladas.
