Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello guys, I have few questions before the server will be released.

1) Is it really worth questing exactly after launch? There might be so many people in the same zone killing 8 quest mobs will take an hour before they actually respawn.

2) Isn't it weird that they have fixed all the bugs but the game client is same? I thought the bugs that wow had was client(data) and not a server issue. Can anyone explain this?

Bugs are all server issue.

About the release, you are probably right.
