here is one quest that was initially doable at dubious faction with COV faction. hardest part was to get the correct sentry kale up one version doesn't give this quest.

it was changed near Dec 2002 you can see post talking about that change in faction their.
Anyhow Basicly you could spend 4 to 5k plate and get to max ally COV faction in a few hours.
ideally make a corpse In skyshrine have a rezer standing by have a druid/wiz port you to great divide do turn in thurgdain get rez rinse repeat. I did this on EQ Mac was amazingly fast.
The quest give 25 pts of cov faction and some pts of yalniak faction per turn in.
Obviously it was nerfed to require warmly faction because it was to easy to get to max ally cov faction and with enough ttime and money max yalniak faction.
