In my experience questing on SOD has always been its weakest point content-wise. However, I would never compare the expanding of Dalaya to that of EQ. It's important to remember that this server is run by people like you and me, and they have very limited resources. All in all, I see SOD growing better and better over time, and it's been this way since I started around Sep of '05.
Interestingly enough, SOD actually removes zones that are the sucks. Recently, an older zone, FR, was given a big revamp into an almost entirely new "face."
I suppose my point is, is that questing is a weaker point for SOD, but overall, I do see some quest development in addition to ongoing development that is making this server better for everyone 1-65.
