I think D2R needs more deep changes. Not only a few more runewords. If they want to make people play other clasess besides Sorcs, they need a lot more. Maybe even nerf a few abilities, and fix some bugs, that I imagine they don't wanna do because of nostalgia. But the thing is, if people want to play classic d2, classic d2 is still there, in comparision to wc3 wich they butchered. Here they can change a lot more, and still retaining the classic versions.
Teleport.This has never been a complicated issue.
