Since release D2R got some nice features beyond original D2LoD.
However … pretty much all features which would work in Classic are not there! Naturally runwords, charms and new cube recipes won’t work but how about
a) Shared Stash (not necessary larger stash which would also be nice)
b) Merc stats and skill updates
c) updatted monster levels in specific areas
d) Terrorzones
e) allow exceptional items to be gambled
f) allow grey socketed armors (gosh something so simple is not there!)
g) allow magic and rare throwing weapons (what’s the point in skipping them?)
