Ok i'll make a long story short here. Leveling in a conventional way won't be possible when TBC hits live because of the number of people everywhere.
Any attempt to level up through normal questing will be reduced to either mindless gankfest which is something i have no intention of participating in or waiting like 2 hours to do anything even remotely meaningful.
So without further ado
1. Will the quest log be reset? Simple question, no need to mention much more here, based on this answer i will make further plans.
2. How viable is to level through dngs, basically Ramparts and the other one forgot it's name? This way seems the most viable ( to me at least) considering the circumstances.
