We got almost all the quests logged in our forums, so they will be completed quickly again anyway, so I have many great items twice and more times, so I can sell them and make a huge lot of money, so I can.. uhm.. can.. er.. I WILL BE RICH!
Huh.. whatever, as long as the questsystem is fixed fundamentally and on base of such an improved system future quests will be expected to be most bugfree, why not?
To not wipe faction-points of course would be nonsense.
Leaving Winch-access untouched I would welcome greatly! People not doing all the quests again because they say they already have Winch access would do better to think twice, since many quests (also the ones to come) require others to be completed previously, as well as certain Winch-quests give fancy rewards. But for people having current plots played out in that region wont have to pause it until access regained.
Although I could sort all issues and stucks of my quests.. for the ones who could not: Yes.
