you know one thing that makes me not thinking playing WOW is that
most of its quests require team work, parties.
however, from D1, D2 to DS2, I mainly play solo.
the reason is that it is almost impossible to find and keep good partners,
people come and people leave, a large part of them sux and trouble.
then I tell myself, no party is better than bad party.
if it is possible to do quests alone, even it could be very difficult, but not impossible,
I would play WOW as well.
