Things changed/nerfed in 1999 not nerfed in Live.

[Vladesch]

Not exactly a nerf but it does severely hurt your ability to level...
Many of the kunark zones don't have safe spots on this server.
For example the area to the s and sw of the crater in burning wood, or outside the giant fort in burning wood.
The area outside the giant fort in frontier mountains.
The area outside karnors castle in dreadlands is safeish in places, but nothing like the nice clear border you had to pull stuff on live.
The eastern zone wall north of the overthere tunnel in skyfire.
The area close around the lake in loio.

As for a real nerf, the inability to drop coins.
(Yeah yeah, I should be happy to pay a tax and buy gems)
